He needs the money with a GnR reunion in his back? I doubt it. It was probably more a mix of vanity/hubris and childhood dream come true.
You're the drummer, Jake, but to me they differ quite a bit, Rudd is behind the beat, Slade slightly ahead.
And anybody reading my anti-Bonham sermons knows what I think of drummers behind the beat!
Let's not even talk about the cymbal work here ... and Rudd sounds like he has issues keeping up with the tempo, but that is of course his style and there are people who appreciate this behind-the-beat thing, I know, but it drives me nuts as a bassist, Bonham and me would have never gotten along groove-wise ...
