"Open Your Box" is a song by Yoko Ono, released on 12 March 1971 as the B-side of John Lennon's single Power to the People. It was remixed and re-released by Orange Factory in 2001.In 1971, Ono's risqué lyrics were received in controversy ("box" is slang for vagina). She sings, "Open your box, open your trousers, open your sex, open your legs, open open open open open". The record was banned from radio in Britain, and was played on-air only when echo was added to blur the lyrics.
