Cambridge Circus was also the name of a comedy revue that played in London in the 1960s. Unfortunately the title sometimes confused audiences, as it was not actually playing at Cambridge Circus itself.
Originally a Cambridge Footlights production, the show starred John Cleese, Graham Chapman, Bill Oddie, Tim Brooke-Taylor, David Hatch and Jonathan Lynn. It played at the Edinburgh Festival in 1963 before opening in London. It then bizarrely toured New Zealand followed by a transfer to Broadway and finally Off-Broadway.
