Did You Know?
Worked with Paul McCartney
and Linda McCartney
on their 1971 "Ram" album, and later with John Lennon
and Yoko Ono
on 1973's "Feeling The Space" and "Mind Games", and Ono's "A Story" (not released until the 1990s) in 1974. Was nervous about Lennon's discovering he'd already worked with McCartney; Lennon's only comment when he did find out was that McCartney "knew how to pick good people."
