David Coverdale - close enough. Please, no Steven Tyler. If you're not a big Jason Bonham fan, Mike Portnoy just left Dream Theater. And Jimmy...my world seem to crumble as soon as I heard "Hot Dog" on 'In Through the Out Door'.
No reforming of Led Zep apparently
Don't know if it is common knowledge or not but I just heard an interview with Robert Plant, who said when asked if Led Zep were going to reform, he said 'no', as he is happy were he is at musically'.
