John Lennon (1940-1980), his son Julian and Yoko Ono pose for
a rehearsal for the Rolling Stones' "Rock and Roll Circus" TV special in
London on December 10, 1968.
John and Yoko performed as part of a supergroup called The Dirty Mac, along with Eric Clapton, Mitch Mitchell and Keith Richards. It was originally meant to be aired on the BBC, but the Rolling Stones withheld it because they were reportedly unhappy with their performance. The film was not released until 1996.
