Underwood ended up getting onstage to perform with the band, named The Heartshakers, to sing the Petty’s duet with Stevie Nicks, “Stop Draggin’ My Heart Around”.

The song was originally released on Nicks’ 1981 solo album Bella Donna, and reached No. 3 on the Billboard Hot 100.

“It’s been a while since I’ve done this one, so I’m just going to hold this for security’s sake,” Underwood said, holding her phone as she got on the stage, “my words, my lyrics.”

She added, “I see that tip jar over there, just sayin’, just sayin’. I think we all need to pay a visit to the tip jar tonight.”
