Okay, I just can't my big mouth shut on this one... As a multi-instrumentalist, I'd give the nod to Jonesy, but not by much. The guy can play anything. But, over-all, Geddy kills everyone. Remember, back in the 70s, long before sequencing and any "cheating" was part of the live gig, Geddy used to play bass (and very complex bass, in fact), keyboards, Taurus pedals, and he'd sing LEAD VOCAL too. And, he did this ALL AT THE SAME TIME. I remember seeing the AFT Kings tour in '77 and asking my friend, "How in the hell does he do all that at the same time without going mental?" And, he was only 24 then... Oh, I forgot to mention that played a fair amount of guitar then too, by way of the double-neck Rickenbacker bass/guitar. I think Geddy could own JPJ on just bass playing alone, but when you factor in all of the things he did AT THE SAME TIME, it'd be hard not to vote for the "skinny kid from Willowdale with the high voice."
