I do agree with Limelight being over played nearly every tour up until now, but still, for what was their last tour, they should've played it. It's easily one of their most recognizable and well-known songs ever. Also it would have been cool if they brought out some more songs never played live or not played often, like Afterimage, Emotion Detector (especially since they completely ignored a good chunk of the 80s material on the R40 tour, but probably because they pulled a lot of it out for the CA tour), Chain Lightning would've been nice, The Trees, La Villa and even Cut To The Chase. New World Man, which hasn't been played since the 2002 Vapor Trails tour, would've been nice to hear also, but they already had Subdivisions and Losing It, so they were good on their Signals load. Speaking of Vapor Trails, even though it isn't a popular opinion of a good Rush album, I enjoyed it quite a bit and have a couple of tracks that I wished they played. Nocturne, The Stars Look Down and I would've loved to hear Earthshine one more time. I would say more early Rush songs, but they did play a lot of their older stuff on R40 anyways like Jacob's Ladder, Xanadu, Prelude, Lakeside Park & Cygnus X-1, though you have to also keep in mind of Geddy's vocal range. But if his voice wasn't a factor, then sure, I'd like to hear: By-Tor, Bastille Day, The Twilight Zone, Something For Nothing & Cinderella Man.
