He played a solo on the Fat Boys “Baby You’re A Rich Man” as well as on the Grammy Nominated cover of “Wipeout” with Herbie Hancock and Terry Bozzio from the “Back To The Beach” film soundtrack.
Side note: That's so funny you bring up "Back to the Beach", because I was just thinking about that film today, with Lori Loughlin in the news so much these days. I'm surprised The Beach Boys weren't in that film. It seems like it would have been a PERFECT project for them to have done a cameo in around that time.
Maybe The BBs were on a short list to perhaps be offered a cameo appearance, but were away on tour or something. I would expect that at minimum they'd have been thrown around as a possible contender, seeing as everyone and their mother had a cameo in BTTB.
