Bonus hidden track
If I Fell - Convention Hall, Philadelphia, September 2, 1964. (CDR trade)
A listing of 30 of the most interesting unreleased Beatles tracks from the book "The Unreleased Beatles: Music and Film" was used as the basis for the compilation. It was compiled by me for the 100 greatest bootlegs blog (March 2016). The sources I have used are in brackets after the notes on each track.
Note that two tracks from Richie Unterberger's list are missing from this post. These have now been officially released on the BBC sessions 'BBC Vol.2'
Beautiful Dreamer - January 22, 1963 BBC session. Saturday Club, broadcast 26 January 1963
Lucille - September 3, 1963 BBC session. Pop Go The Beatles, broadcast 17 September 1963
The following track was not used:
If I Fell - Early 1964 John Lennon demo vocal and acoustic guitar
This is a very lo-fi recording with extremely low sound levels (Complete Lost Lennon V15t19)
Since I first posted this, the Esher demos have been officially released on the expanded edition of the 'White Album'. Three tracks originally included have therefore been omitted, the remainder of the tracks are as far as I know still unreleased.
