June 1, 1974 is a live album of songs performed at the Rainbow Theatre in London on the titular date. The album is officially attributed to Kevin Ayers, John Cale, Brian Eno and Nico, although other well-known musicians, including Mike Oldfield, Robert Wyatt and Ollie Halsall, also contributed to the concert. It is also informally known as the ACNE album, i.e. "Ayers, Cale, Nico, Eno". The cover photograph was taken by Mick Rock in the foyer of the Rainbow Theatre shortly before the concert began. The bemused stare between John Cale (right) and Kevin Ayers (left) is explained by the fact that Cale had caught Ayers sleeping with his wife the night before the show.
Other songs that were performed but did not make the LP include Kevin Ayers' "I've Got A Hard-On For You Baby" (with Cale on backing vocals), John Cale's "Buffalo Ballet" and "Gun", and Nico's "Janitor of Lunacy" and her rendition of "Deutschland Über Alles".
