Great thread everyone. Thought I would chime in:
Red Barchetta - the outro with the bass and drums is just awesome, then Alex re-enters and Geddy picks up on his melody. Sounds fabulous live; they cut the song off too soon on the studio version!!!!!
A Show of Hands - the transition from the 3 Stooges intro to The Big Money. That opening chord sounds HUGE!!!
Xanadu - imediately after the transition from the "ethereal" to Alex picking the arpeggio-like part - Neil plays the downbeats and all of a sudden hits the snare just before one of the downbeats (then goes on to three drum hits, then four . . .) - (hope I explained this one ok)
Secret Touch - during the "bridge" I guess you might call it, Alex is rocking along by himself then Geddy and Neil come in with those low fast accents. AWESOME!!!
