A rare cassette recording of John Lennon and Yoko Ono has been sold for $58,300 (£43,000) at an auction in the Danish capital Copenhagen, reports the BBC.
The 33-minute audio track, according to the report, was made by four Danish teenagers more than 50 years ago, and just months before the Beatles announced their break-up.
It features an interview with the couple and what is believed to be a never-released song.
The auction house said the cassette tape would probably be bought by a museum or collector before it opened bidding on Tuesday.
The buyer, who remains unknown, made a telephone bid for the cassette, which was sold along with photographs of the schoolboys with Lennon and a copy of a school newspaper.
In January 1970 a group of schoolboys set out to meet the iconic musician and interview him for their school newspaper.
“We were a bunch of 16-year-old hippies,” says Karsten Hoejen, who made the recording. They were mostly interested in Lennon and Ono’s peace campaigns, he says.
