Relax, Aerosmith fans: Steven Tyler says he isn't leaving the band.

Tyler made a surprise appearance with guitarist Joe Perry and his band Tuesday night at a New York City venue. Tyler told the crowd: "I am not leaving Aerosmith."

Rolling Stone and Billboard magazines report the two then launched into their song "Walk This Way."

The appearance seemed to put an end to speculation about the band's future.

Perry recently tweeted that Aerosmith was "looking for a new singer to work with" and told the Las Vegas Sun that Tyler had quit, at as far as he could tell.

The 61-year-old Tyler was injured when he fell off a stage during an Aug. 5 performance in South Dakota, and the band canceled the remainder of its summer tour.
