London '66–'67 is an EP and film of Pink Floyd music created as promotional trailer for Tonite Let's All Make Love in London, containing two "lost" tracks—an extended version of "Interstellar Overdrive" and a previously unreleased track "Nick's Boogie" released as VHS on September 29, 1994. These tracks were originally recorded for Peter Whitehead's film Tonite Let's All Make Love in London in 1967, and the former appeared in edited form on the soundtrack album.
