I think this recent interview question and answer with Geddy is quite telling. I'm not sure people appreciate how difficult it is to do what they do night in and night out. I believe it's reasonable to expect them to pick songs that they enjoy playing AND that might be, at least, a little easier on Ged's voice.
Your first concert for the upcoming tour is Sept. 7 in Manchester, N.H. Is touring easier these days?
Easier? I find it more stressful than when I was younger. I think the physical part of it takes its toll on me, and the other guys I know for sure. Staying healthy becomes a more difficult challenge, and as the tour winds on, nerves fray in a different way than they used to. Although, you have more confidence than when you were younger, and more command of your instrument [and], as a result, more command of your audience's attention, which makes it easier. There is kind of a physical price you pay as the tour winds on, whereas when I was younger I could be in almost any condition, get out there and bang it off. I'm grateful for the audiences that we have, wherever we go. But it's a difficult thing for me to do right now.
If they played all the 70's stuff we ALL would love to hear them play Ged's voice would probably be shot by show #10.
