Perry canceled a solo show scheduled for April 5 in Niagara Falls, N.Y., so he can recover from knee surgery, spokeswoman Marcee Rondan said in a statement released Monday.

Rondan said Perry has needed knee surgery for two years but put off the procedure so he wouldn't miss any Aerosmith tour dates.

The 57-year-old's knee finally gave out early this month after a pair of performances with his two sons. That prompted his doctor to schedule the surgery for March 18.
