Eric Singer is a far superior drummer and much better singer.
In Paul's new book he states that before the reunion in 90's, Tommy Thayer had to teach Peter all the drum parts. So, a guitar player had to teach Peter how to play the drums and re-learn the songs that HE originally recorded. Peter = fucking loser.
Tommy also taught Ace all his guitar parts. Ace = fucking loser.
Both of them got mad as hell at Tommy several times, cursing and lambasting him and he had to sit there and take it. I really hope Tommy got paid well.
