I'm not a huge fan of the band, but their concert was one of the best I've ever been to. You had Geddy singing, playing keyboards with his right hand, hammer-on bass with his left hand, and foot pedal bass (like on an organ) with his left foot. I'm assuming he was using his right foot to stand on.
I swear I saw Neil throw up drumstick 30 or 40 feet in the air, and catch it and keep drumming in time without looking up. It may have been a trick, or the, er smoky atmosphere, but it looked real.
