"I Love Rock 'n' Roll."

Underwood talked about the unexpected collaboration before the show. She revealed to that the idea came about after "bumping into each other" several times over the years. Underwood thought there was a chance Jett would be interested in teaming up with her, and decided there was no harm in asking.
