The song Taxman by George Harrison opened the 1966 album Revolver. The version that appeared there was take 12 recorded/mixed 20–22 April, 16 May and 21 June 1966. It featured an ending that was made up of an overdub of the McCartney guitar solo from the middle eight. The album of alternate versions, Anthology 2 (released 1996), featured a version that ended “cold” with the word “Taxman”.
Recently a version has surfaced on an Emidisc acetate from 1966 that bridges these two versions in that there is an extended ending of an overdub, not of the middle eight guitar solo but with the driving bass riff that underpins the song (and that was incidentally used by the Jam on their song Start! From the album Sound Affects).
It came in a group of acetates that also included a new rough mix of And Your Bird Can Sing with a shaky lead guitar track and different drumming in the outro, also from Revolver.
