Rush closed out the 2007 world tour with a literal bang when during the song "Far Cry" some pyro exploded behind the band, and took out Alex Lifeson's amp along with it. It happens at the 3:45 mark and couldn't have been timed better. The lyrics at that point "You can almost see the circuits blowing" and it's amazing that Geddy and Neil continue the song by themselves. I love Geddy's quote at the end "You have to excuse us. Alex's amplifier seems to have blown up here. So if you can give us just a few minutes here, we'll continue properly."
