@spiritofradio, Jim Keltner met Jeff Porcaro when the latter was only 16 years old (and already a monster player). Jim says Jeff told him what an influence Jim had been on his playing, and Jim told him to listen to Roger Hawkins (in a Modern Drummer interview, Jim said he wished he played more like Roger).
Hawkins is one of my three all-time favorite drummers, though fans of Neil Peart-style drumming (or that of, say, Ginger Baker, or Keith Moon, or any other Rock band drummer) may not understand why. As Duke Ellington said (also attributed to Count Basie and Miles Davis): "The notes you don't play are as important as those you do." Words of wisdom.
