John Lennon

McCartney has been busy in quarantine. The artist speaks about his new album, McCartney III, the quirks of writing love songs and remembering his late friends John Lennon and George Harrison.

In December of 1968, some of the biggest names in rock and roll came together to film The Rolling Stones' Rock and Roll Circus. The film was recently given a 4K restoration.

The never-before-seen clip, of the two former Beatles recording Lennon's "How Do You Sleep?" in 1971, comes ahead of the Oct. 5 release of a 6-CD box set, Imagine - The Ultimate Collection.
