Just announced: Elton John/Billy Joel at Citizens Bank Park

Billy Joel and Elton John's joint tour will stop at Citizens Bank Park at 7 p.m. July 30, while the Phillies are on a West Coast swing.

Philly hosted the piano men's first-ever match-up, in 1994 at the late Veterans Stadium. (So why aren't they playing the Spectrum before its demolition?)

Tix on sale at 10 a.m. Saturday through ComcastTIX at 1-800-298-4200, on line at ComcastTIX.com, in person at the Wachovia Center box office or at select Acme Markets.

Press release says the two will open the concert together with a series of duets, playing twin pianos and trading vocals. Each artist will then perform a set with his own band. The grand finale reunites the two at center stage with their supporting musicians for a closing encore.

Not on the press release: Ticket prices are $49.50, $95 and $175.
