Big Punisher, Mya, and the Cherry Poppin' Daddies will find themselves hobnobbing with the wrestling world's finest when they perform at a party to launch Wrestlemania XV later this month.Five other big name acts are also expected to be added to the bill, which is set for Philadelphia's Pennsylvania Convention Center on March 27, the night before Wrestlemania XV. The kick-off party will be broadcast during a one hour special airing on the USA Network at 10 p.m. Eastern time. Two as-yet-unannounced musical acts will also perform at Wrestlemania itself, which is slated for March 28 at Philadelphia's First Union Center. In addition to the music, there will of course be some wrestling as well, as Stone Cold Steve Austin will take on The Rock on a card that also includes Vince McMahon, Mankind, the Undertaker, and female wrestler Sable (who will be featured in the April issue "Playboy"). The big event will air live on pay-per-view at 8 p.m. Eastern time and tickets cost $80.
