At the Rainbow is the first live album from the Dutch rock band Focus, released in 1973. The album was recorded at the Rainbow Theatre in London on 5 May 1973. A studio album was initially slated for release, but it was shelved due to disagreements within the band. (An album compiled from the tapes of these sessions was later released with the title Ship of Memories.) At the Rainbow was released instead. Producer Mike Vernon is known to have mixed Live at the Rainbow for a quadraphonic release. The same show that composes this disc was filmed for the know BBC program Old Grey Whistle Test. However, the program was never officially released by the band, which has not happened with other BBC broadcasts (In Concert 1973 and other 1971/1972 that are inserted on dvd Focus - Masters from the Vaults). Possibly the program has been deleted from the archives of the BBC, and only exists in bootleg format, recorded from a Brazilian program of the late '70s. IT's a big shame, considering the quality of the live album.
