Watching those Beatles videos that were posted, I'm curious about this one. Is it from the above-mentioned Rock 'n' Roll Circus? Lennon accompanied by Keith Richards and a very young Eric Clapton that I didn't even recognize at first. 
The "Real Love" video from the Anthology set very nearly made me tear up.
Yep, that's The Dirty Mac (If you haven't seen R 'n' R Circus, rent it). There's also a jam bit following Yer Blues (that's Mitch Mitchell on drums) with violinist Ivry Gitlis ,& Yoko in full wail mode. That's my fave Beatles cover involving a Beatle. It was done with very little rehearsal (Wyman was a bit miffed they didn't ask him to play bass). It's also a tad sadly ironic ,as it contains the line "feel so suicidal, just like Dylan's Mr. Jones", a reference to Bob's Ballad of A Thin Man, reputedly about Brian Jones, who's a bit of a ghost here. Beggar's Banquet (from this year) was his swan song. He did play sax on The Beatles You Know My Name, possibly his last recorded performance.
