Cobra Starship were announced as Headliners for next weeks’ The Rock ‘n’ Roll Philadelphia Half Marathon, but now R’n'R Philly announced American Idol star Haley Reinhart as headliner for the concert on Sunday, September 16.
Due to an unexpected scheduling conflict, Cobra Starship will not be able to perform at the finish line festival. The band extends their apologies to fans for any inconvenience this may cause.
