A night after U2 pulled a tribute band on stage, they brought a young woman on stage to show off her guitar skills.

Bono picked a woman named Stephanie from the audience at Toronto’s Air Canada Center Tuesday night and let her play acoustic guitar on “Angel of Harlem.” She impressed the band so much that he announced that she wanted to play “All I Want Is You.” After she proved she knew the song, the group launched into it with Bono adding in lyrics from Van Morrison’s “Into the Mystic” at the end. Check out the performance on YouTube below.

Dave Grohl from Foo Fighters was spotted in the audience at the show, so Bono sang a snippet of Nirvana’s “Smells Like Teen Spirit” at the end of “The Electric Co.”
