Forty years ago, two of music's biggest stars walked into BBC Radio 1 and sat down to review the week's new releases.
Michael Jackson and George Harrison spent the next 90 minutes discussing singles by Foreigner, Nicolette Larson and The Blues Brothers, as well as the stories behind their own songs.
The BBC discarded the show, keeping only a short clip. But now a rare recording has been found and restored.
Excerpts will be broadcast in a special documentary this weekend.
Listeners will hear Jackson, just months before releasing Off The Wall, discuss how Motown refused to let him write his own music; while Harrison explains what it was like to work in the songwriting shadow of Lennon and McCartney.
At one point, Jackson turns to the former Beatle and says: "Let me ask you a question, did you guys always write your own stuff from the beginning?"
