“It goes without saying that Chad Kroeger has such an engaging voice. So right there, you know you’re probably going to get something of an unusually high quality.

“ZZ Top’s original version was almost captured by accident. I was singing in a fake falsetto. Usually, falsetto can be kind of thin, but what we did had a richness and a grit to it. Chad doesn’t have to do anything by accident. What he does is real, and he hits those high notes. It’s like Little Richard meets John Fogerty meets ZZ Top in another world. [laughs]

“Their version is thrashier and trashier, and the end result is a real rock song. It’s not techno-this or electronica-that. It’s straight-ahead rock. I was very curious as to what they’d do with the middle solo. There’s enough reference points so you’re never left out in the cold, but there’s originality there, too.

“Besides, who can really play the crazy stuff we play? I can hardly play it!” [laughs]
