"I've known about Glenn from the Trapeze stuff," says Cobb of the former Deep Purple rocker. "My favorite era of music has always been maybe '65 to '73 and he was there.

"It was crazy to hear the stories: he knew my favorite bands, he was hanging around them, he played all the legendary places and recorded in legendary studios. I mean, God, you could make a freakin' reality show on that guy and the things he's been through and done and who he is now. It's amazing."
