Robert Wyatt - The Pink Floyd connection

Nick Mason: I'm a believer (7" 1974) (production and drumming)
Syd Barrett: The Madcap Laughs (1977)
Syd Barrett: Opel (1988)
David Gilmour: In concert (DVD 2002)
David Gilmour: On an island (2006)
Nick Mason: Nick Mason’s fictitious sports (1981)

Since Richard Wright guests on Gilmour’s DVD, only Roger Waters is missing a Wyatt connection on record? But hey, Pink Floyd played a benefit concert after Robert was paralysed, so let's be generous!
