Did you know that Jonathan Cain has a brother who's a professional drummer? His name is Tommy "Mugs" Cain and he worked on Michael Bolton's "The Hunger" along with Neal and his bro and Michael Baird, and Randy Jackson

He also had to have played with Tane Cain on The Terminator soundtrack. Plus his website says he played with Gregg Rolie- I'd like to know when that was.

This does beg the question, why didn't Jonathan ask Mugs to play on "Raised On Radio", or join Bad English and/or Journey? Not that I'd want Deen to have never joined the band. He's an invaluable asset as a singer as well as drummer.
He should totally be playing with Neal's son and Jon's daughter in American Beauty.
