“This might have been the first song that I heard. The riff is just amazing. Like it is with so many Rush songs, it’s all about the energy of Alex, Geddy and Neil playing together. When you’ve got that, you’re off, you’re flying!

“There was a demo of it, but we changed a lot of things around for the actual recording. I’m not sure if there were actual drums on the demo. Things were happening pretty quickly.

“For Alex’s guitar tracks, we used his Les Paul Goldtop and his tobacco sunburst 335. We put those through a Marshall and a Bogner.

“We recorded in Nashville, and the whole thing took only two days – drums, bass and guitars in one day, vocals the next. Even though we did Caravan and BU2B first and then took a break for the band to go on tour, the energy of those two songs carried through the rest of the record.”
