'Yessongs', the film, documents performances from shows Yes played at The Rainbow Theater in London on Dec 15 and 16, 1972, during the 'Close to the Edge' tour. The album 'Yessongs' is not the soundtrack of the film, but a record of various performances from the the 'Fragile' and 'Close to the Edge' tours. Only two performances are the same on the album and film: 'Close to the Edge' itself, and 'Wurm', the closing section of 'Starship Trooper'.
In select theaters the film was presented in 4-channel sound, and billed as 'quadraphonic', though actually the sound was three front channels and one rear channel rather than true 'quad'. The audio on all VHS, laserdisc and DVD releases of the film as of 2009 has been upmixed from mono.
