Billy Joel and Elton John's Face 2 Face show originally scheduled for Sunday, November 22 at the Pepsi Center has been pushed back to February 22. Any tickets purchased for this Sunday's show will be valid for the rescheduled date, and refunds are available at point of purchase. The two have have had to postpone recent gigs due to concerns over John's health -- who was suffering from an e-coli infection and influenza -- and, more recently, Joel's health.
