@goofyfoot: The drummer you hear on All Things Must Pass is Jim Gordon. He is also the drummer on the Derek & The Dominos albums (as well as the writer and player of the piano coda on "Layla"), Dave Mason’s Alone Together (along with Jim Keltner), some of the Delaney & Bonnie albums, The Notorious Byrd Brothers, Early Joe Cocker albums, late period Traffic, Zappa’s Grand Wazoo, Steely Dan’s Pretzel Logic, Art Garfunkel’s Angle Claire, and hundreds of other recordings.
Gordon turned pro at age 17, hired by The Everly Brothers to be in their road band (they also hired Warren Zevon to play piano and lead the band). He is as fine a drummer as I have ever heard (better imo than even Keltner), one of the all-time greats. He unfortunately liked drugs a little too much, and they along with his mental problems (he heard voices) led him to stab his mother to death (the voices told him to). He has been in prison since 1984. Genius is often accompanied by mental and/or emotional instability. When off his meds Brian Wilson also hears voices, but they don't instruct him to murder Mike Love. ;-(
