Cleeds---Au contraire! Lots of Rock 'n' Roll swings, even The Beatles. Ringo is known to swing pretty well; listen to "Kansas City". Rock 'n' Roll drumming was created by New Orleans drummer Earl Palmer, one of Max Weinberg's (Bruce's drummer) heroes. Terry Williams of Rockpile and Dire Straights swings like crazy, as did (R.I.P.) Tom Ardolino of NRBQ.
But "swing" does not just mean to play in a "shuffle" rhythm, it means being loose and flexible, reacting to what the other musician's are playing. Max Weinberg is a very "stiff" drummer, like a boring drum machine. One drummer who values swing a lot is Charlie Watts, though he doesn't get much opportunity to display his abilities at it.
I suppose one could differentiate between Rock and Rock 'n' Roll, but that could lead to a LOT of disagreement!
