London '66–'67

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. Originally released in full on the 1990 See for Miles Records UK reissue of the soundtrack album, they were the earliest Pink Floyd recordings available commercially before the limited release of 1965: Their First Recordings in 2015.

The EP was originally issued in 1995, then reissued by Snapper Music (SMACD924X, 2005) on 13 September 2005, as a remastered CD and a DVD featuring the entire film plus excerpts from the original movie. The EP is considered an early example of the jazz fusion genre, incorporating jazz-influenced improvisation to their psychedelic compositions.
