Below I give some pointers to obtaining versions of the less well travelled Beatles' songs
A search on Amazon produces about 200 versions of songs called Misery but very few of these are I suspect the Beatles’ version. As well as the Flamin’ Groovies record, there are definitely versions by Kenny Lynch (awful), Peter Lipa (I suspect not sounding very much like the song), and the Parrots. The latter is from a Japanese (?) CD which apparently covers the entire Please Please Me album and 3 early singles called “Please Please Me The Parrots Live at Abby (sic) Road”. I have a suspicion it might be by a tribute band which I don’t count as a proper cover. There may also be versions by Forum Quorum, All Night Workers, Dynamics and Dick Rivers but I could not guarantee it. For years I thought this had never been covered but in fact Les Lionceaux did a cover (Je Suis Fou) in French in the early 1960s. This is on a fine CD by the group called Twistin’ The Rock Vol 16, though it only seems to be available in France. The only other one I am sure about is from the same Parrots’ album that Misery appears on but this may be just a tribute band. There is an internet-based suspicion that the song of the same title done by a chap called Zach David, or possibly Zach Davids, may be the Beatles’ song, but I am not sure. The version I have chosen is actually called C’est Fou Mais C’est Tous and it is on a CD of French language covers titled Studio 101. Steven King does a solo guitar version on one of his Beatling CDs (available from his website if nowhere else). There is also a Phil Spector produced version by The Treasures which is available on the triple CD Back to Mono 1958-1969. There's a baroque version by Joshua Rifkin which sounds nothing like anything and ones by Count Basie and Stackridge too. Maybe also by Los Idolos. Apart from Les Lionceaux’s version, there are ones by The Beach Boys, Brinsley Schwarz and April Wine. I have not heard any of these last three. This version is the only one of which I am aware. It is on You’ve Got Me Humming – the Best of The Hassles, which was Billy Joel’s group before he was famous. Even then it was only done as a demo. There are a few songs called this but the only version of the Beatles’ tune I can find is the Hub Kapp one. It is on Wallace & Ladmo’s Greatest Hits. I got this off ebay without too much difficulty and it seems to be available from real shops from a quick internet search. Apart from the Geoff Gibbons one, I can see mention of one by the Barbara Casini Quartet and one by Yukihiro Takakashi, but little else. The Geoff Gibbons one is on an excellent various artists double CD called It Was 40 Years Ago Today from which a dozen of my selections come. A must buy ! This is relatively seldom covered, though there would appear to be versions by Punkles, Silver Convention, Kingsmen and Queers, as well as an uninspiring one on the Beatlesgrass bluegrass CD. I have a rather boring vinyl version of this by the Leo Chauliac Orchestra and I also read of a version by Les Faux Freres. The Gerard Pansanel version is also by Antonello Salis and appears on a CD called Beatles / Cinecitta, which contains guitar and piano duets including a rather beautiful Strawberry Fields. Thank goodness for the Teenage Fanclub one because the only other one is an obscure one I have not heard by Jacob’s Trouble. I have the former on a free CD distributed with Uncut magazine and I am not sure if it is available elsewhere. (I got mine off Ebay for 50p!) Nothing on Rubber Soul can really be called hard to find ever since the release of This Bird Has Flown, a 40th anniversary various artist tribute to the entire album. It is pretty good too, though the version of this song by the Yonder Mountain String Band is not a particular highlight. The Out of Towners’ version is on another various artists tribute album called Without The Beatles – I stole the title for my version of With The Beatles. Apart from those there is a rumour that there are versions by Fabrice and The Music Company, and various songs called the same thing, but none I am sure is the Beatles’ one. My research reveals covers by Music Company and Don Sebesky, neither of which I am afraid I have heard. The only other I am sure of is the one on This Bird Has Flown, which is by Mindy Smith. Obviously this is on the This Bird Has Flown tribute album, done not that well by Sufjan Stevens. It is definitely on vinyl done by Orphan. Amazon reveals a lot of similarly titled songs but I cannot be sure any is the Fab Four version. Well, there is the Connie one, and the one on This Bird Has Flown – by Ben Kweller. Then there was an old B-side by the one and only Roy Orbison. But not sure that there are any others. This song is largely by-passed by coverers maybe due to its difficult Indian sections. There is the version by Les Fradkin from a CD of almost the same name (Love You 2), one by the guitarist Steven King (available from his website at http://www.kingofguitar.net/), and two older ones by Bongwater and the Don Randi Trio (which I have not heard). There is a live version of this released in 2005 by Andrew Gold as a bonus track on a re-issue of his album All This and Heaven Too. Apart from that there is a dull one on the Beatlesgrass compilation CD and the nice solo guitar version by Steven King. Aside from those nothing I know of. Jamie Hoover does this on the Harrison tribute album He Was Fab. Apart from that, we are left with the Phoaming Edison one and an obscure reference to a version by The Empty Set, which may or may not exist (I could not see reference to it on their website, though there is reference to a version of Happiness is a Warm Gun). Phish of course do this on their album. John Kilzer has a version and a reprise on the Fried Glass Onions Vol 2 CD released in 2005. There are also songs called this by Link Quartet and Godless Wicked Creeps but I do not know whether they are the same song. I originally thought for some reason that there were no covers of this, but I now discover there are more than you can shake a stick at – provided you can only shake your stick at two. There is the Pixies live version, one by Phish (also live from their entire White Album except Good Night concert), and one by Das Damen which I have not heard. Quite a rarity this. Only the Young Blood one, the Phish one and one by Klaus Beyer which I know of. The former is pretty easy to get – it is quite often on compilation CDs, including the excellent All You Need Is Covers. The latter is on Exotic Beatles 2. The Matmosphere one is good and weird and comes from the Without The Beatles CD mentioned elsewhere. There is one by Beat Generation on the first Fried Glass Onions Memphis collection which is good and short. There is one by Jeff Healey which I have not heard and one by Billy Butcher which I cannot guarantee is the right song (though it probably is). Oh and the one by Phish obviously. Phish, obviously, and the Paul Weller one, but only other I can find is by Ramsey Lewis, and I don’t know whether this still available or not, or indeed what it sounds like. There are of course plenty of covers of Revolution. There is only one cover of Revolution 1 which goes under that name – the one by Phish of course. However, some of the covers of Revolution sound more like the No.1 version, so I don’t know whether to call this a hard to find cover or not. There are 3 others that I know of – one by Bullangus, one by the Dons of Quixote (on the 40 Years Ago Today tribute album mentioned elsewhere) and one by They Might Be Giants (on the Songs From the Material World album, a tribute album released after George’s death). I have the last 2 and they are both good but prefer the Ella version, which is easy to get hold of. I am pretty sure that only the Kurt Hoffman and the Phish versions exist. The former is available on a number of compilations and is easy to obtain from Amazon. Apart from the SHT version there is obviously one by Laibach (because they covered the whole album). However, it is a bit of an acquired taste, the Laibach album, bearing little resemblance to the Beatles’ tunes. Other versions advertised on Amazon are by Kim Stone and the Chris Lightcap Quartet. I also read of a version by God Street Wine though whether you can still get it I do not know. This is not that hard to find in fact. There are ones by Goran Sollscher, Franck Pourcel, Laibach (obviously), and one on a Harrison tribute album which I think comes from Japan called Something. There are lots of things called this on Amazon but none I think is the Beatles’ song. I think Laibach may do the only one. There are some songs with the same title out there but I think the only cover is the one by the Surphonics. It is on a CD called Are You Being Surfed ? on Rarity Records but you may have to go outside of Amazon to find a seller. Please note the John Hiatt song of the same name is not this one. There are at least 4 versions of this, by The Trimatics, the Punkles, the Team-Beats, and one on the German CD Das War Eine Heute Tag, which I have yet to obtain but think I will do. This is quite rare. Gerard Saint-Paul and Sex Clark Five are the only other versions and I have not managed to track them down. Even the Tommy B-side has proved elusive though I have it as a soft copy.
