London '66–'67 is an EP and film of Pink Floyd music, containing two "lost" tracks—an extended version of "Interstellar Overdrive" and a previously unreleased track "Nick's Boogie".

These tracks were originally recorded for Peter Whitehead's film Tonite Let's All Make Love in London in 1967,[3] and the former appeared in edited form on the soundtrack album.

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.
