That's just one of those things that are never going to happen. If you don't see somebody for a while, there's the old thing, 'Absence makes the heart grow fonder.' Well, we haven't had absence," Corgan tells Rolling Stone.
"The things that have happened between us in the interim haven't been good. There have been lawsuits and lots of stupid stuff. It's only made it worse. If it was bad before, it's really bad now. Jimmy and I aren't enemies – he's just off doing what he wants to do, as he should. There's not super bad blood between me and Jimmy that we'd never get on stage again.
