The Dirty Mac

The Dirty Mac was a name given by John Lennon to a temporary supergroup he organised in December 1968 that featured Eric Clapton, Keith Richards, Mitch Mitchell and himself (as "Winston Leg-Thigh"). The band assembled for a one-off performance on the Rolling Stones' TV special titled The Rolling Stones Rock and Roll Circus. The Dirty Mac played Lennon's Beatles composition "Yer Blues" and "Whole Lotta Yoko", an extended blues improvisation in which they were joined by Lennon's wife Yoko Ono and violinist Ivry Gitlis. The TV special, which included appearances by the Rolling Stones, the Who and Jethro Tull, among others, did not air as originally planned and was not released officially until October 1996.

Lennon and Clapton later appeared together on the first Plastic Ono Band album, Live Peace in Toronto 1969, which also includes a performance of "Yer Blues".
