Unfinished Music No 1 Two Virgins by John Lennon and Yoko Ono, released on the Apple label in November 1968, value £3,000

IF YOU managed to buy a copy of this album, the chances are that you played it once and never again. Only 5,000 copies were released in the UK, so overnight it became what is now known as a limited edition. It was one of the first releases on The Beatles new Apple label and John and Yoko's first joint venture was awaited by Beatles fans everywhere. This was probably the first music album banned from being displayed to the general public. The cover depicts John and Yoko standing totally nude in a picture taken by John using a camera with a delayed action timer. The back of the cover shows a rear view of the couple looking over their shoulders. When the master tapes, including pictures of the forthcoming album, reached Apple executive Peter Brown, he thought he was the victim of a joke and locked them away in a cupboard intending to throw them out and sack the pranksters responsible.

EMI, which owned Apple records and had distributed The Beatles records worldwide, released the album in a brown paper bag with a round hole cut out near the top showing John and Yoko's faces. In the USA, the cover was the subject of an obscenity trial. Experts for the defence claimed the pictures were in the tradition of the Christian story depicting Adam and Eve. The judge threw out the claim and the record company lost its case.

20,000 copies were released in the USA where the album peaked at No 124 in the album charts. The music, if you can call it that, was mainly a series of taped loops and sound effects, one track was just two minutes of silence. Many purchasers thought that track was faulty and took it back to the record store only to be told there was nothing wrong, it was produced that way. Imagine sitting at home with your tape recorder switched on and picking up random sounds, noise and snippets of conversation for about 30 minutes or so - that is a general synopsis of this album.

Despite being universally panned by fans and critics alike and even with a limited number of pressings, it is still deemed as being very collectable.
