& to continue offtopic slightly, here's Bobby Rondinelli's 2 cents, ( arguable THE best drummer to play with the Sabs. Big statement I know). He was on Cross Purposes. Ritchie Blackmore used to sing his praises in interviews back in early 80's when he was in Rainbow. G-R-E-A-T drummer he called him.
RNRU : What was the main difference between working with Ritchie and working with Tony?
BR : There weren't that many differences. Tony was really easy going. He'd say, "Play what you want," basically.
