RICKY CASTRATA
Do they mean Richie Cannata? This might be a joke name for him.
JOE POLLARD
Joe briefly played drums for The Grass Roots in early 1972. I think this was before he was with The Beach Boys
JOHN RENNER
Renner played sax with The Beach Boys in 1991.
EDDIE TUDURI
Eddie was with the Beach Boys sometime in the early 70s, it says on his website. He's also played drums with Chilliwack, Rick Nelson and others.
