Naturally, the tour will be touching down in Philly thanks to R5 productions. You can catch them here in Philly at the Mummers Museum at 2nd and Washington Avenue. Pick up tickets at Spaceboy (704 South Street), from Ticketweb or call 1-866-468-7619 (toll free). Oh yeah, did I mention its $22 and includes a "Full Real Deal Four Hour Open Bar (all you can drink - beers, wine, mixed drinks etc)".
