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."
