"Dirty Mac"

The Dirty Mac was the name of a British supergroup which consisted of John Lennon, Eric Clapton, Keith Richards and Mitch Mitchell that John put together for The Rolling Stones' ill-fated TV special entitled The Rolling Stones Rock and Roll Circus. Recorded on 11 December 1968, this was the first time that John, who was still with The Beatles, had performed in public without the other Beatles. The Dirty Mac recorded a rendition of the Lennon-penned Beatles track "Yer Blues" with Yoko Ono on stage sealed in a black bag, and then went on to back up Yoko Ono and violinist Ivry Gitlis on a track called "Whole Lotta Yoko".
