It seems Steven Tyler has quit as lead singer of popular band AeroSmith.

In an interview with Classic Rock magazine of Britain Tyler said he has pulled out of a band tour of South America and that his upcoming plans will focus on “brand Tyler.”

In that same interview, guitarist Brad Whitford mused on the wisdom of trying to replace Tyler but concluded “if somebody was willing to do it and the chemistry was right, why not?”

Although Steven Tyler did not definitively state that he was quitting the band, Perry apparently interpreted his words as such. Perry told the Las Vegas Sun last week: “Steven quit, as far as I can tell.”

Perry also issued a series of Twitter posts that paint a picture of a band divided, including one that says the last time the pair spoke on the phone, Tyler hung up on him. “What about [the] fans?” Perry said. “The people that also love him and put him where he is after 40 years? And I gotta read it on line?”
