So guess who Taylor Swift invited to perform on stage with her at New York City’s Madison Square Garden on Monday, Nov. 21? That’d be Johnny Rzeznik, the lead singer of alt rock hitsmiths Goo Goo Dolls. The band originated in Buffalo, which is way up north in the Empire State. But they are still technically from New York so they fall in line with Swift’s tradition of inviting guests from the state in which she is touring to come on stage with her. The pair performed the band’s pretty, mid-’90s smash ‘Iris,’ a moving ballad, which is right in Swift’s wheelhouse.
