Video: 'John lennon & Yoko Ono - Unfinished Music No. 1: Two Virgins' (3 videos)

(Saturday, May 4, 1968) — Unfinished Music No. 1: Two Virgins, the first of three experimental albums released by John Lennon and Yoko Ono on The Beatles’ new label Apple Records, was completed early this morning during an all-night session of musical experimentation at John’s home studio at Kenwood, while his wife, Cynthia Lennon, was on holiday in Greece.

“My ex-wife was away … and Yoko came to visit me. … instead of making love, we went upstairs and made tapes,” Lennon told David Sheff in a 1980 interview for Playboy. “I had this room full of different tapes where I would write and make strange loops and things like that for the Beatles’ stuff. So we made a tape all night. She was doing her funny voices and I was pushing all different buttons on my tape recorder and getting sound effects. And then as the sun rose we made love and that was Two Virgins.”

The album, featuring the couple naked on the cover, was released on Nov. 11, 1968, in the U.S. (Nov. 29, 1968, in the UK).
