If you watch the Hemispheres Prelude from the Counterparts bootleg, Geddy's singing is extremely forced and pitchy, and that was 1993-94. I can't imagine what it would sound like in 2012.
Going off of what songs they usually play, we can suspect these songs below. I feel pretty much guaranteed that all of these will be played
Tom Sawyer
Limelight
YYZ
Freewill
TSOR
Working Man
Closer to the Heart
Subdivisions
2112 overture/temples
Then a few songs from CA
Clockwork Angels
The Anarchist
Carnies
The Wreckers
The Garden
Seven Cities of Gold
Headlong Flight
