A cassette tape with a recording of an interview with John Lennon and Yoko Ono and what’s believed to be an unpublished song has been auctioned off in Denmark for more than $58,000. The recording was made by four Danish teenagers in 1970 who interviewed the couple for their school newspaper and includes Lennon and Ono singing two songs, “Give Peace a Chance” and “Radio Peace,” which was never released.
