It's no secret that as Rush makes their way around the world on their Clockwork Angels tour that the clock is ticking on their days as a touring band.

Geddy Lee says, "How much longer can we go out there and play three-hour shows at that peak level... There comes a point when you just have to accept that you're approaching 60 and that maybe three hours of blistering rock is for a younger man... So maybe it's just inevitable that Rush tours down the road -- if all goes well and there are Rush tours -- aren't three hours long."
