From the wiki: “‘Old Brown Shoe’ was written by George Harrison and would be released by The Beatles as the B-side to ‘The Ballad of John and Yoko’. The song was recorded during the sessions for the Abbey Road album, first by the group over a three-day period while participating in a Let It Be film session at Apple Studios in January 1969. Harrison then made a multi-tracked solo demo (featuring only piano and electric guitar) at EMI Studios on 25 February 1969. There is some controversy over whether Harrison played bass on the completed album version, recorded in April 1969. In a two-part Creem interview (published in December 1987 and January 1988), Harrison appears to confirm he played bass on the recording:
‘Creem: You also told me you played bass on ‘Old Brown Shoe’.
George: It’s like a lunatic playing.
Creem: It sounds like McCartney was going nuts again.
George: That was me going nuts. I’m doing exactly what I do on the guitar.'”
