So much for that Temple of the Dog reunion some people were hoping for at Sunday's Made in America concert.
Pearl Jam are still headlining, but Soundgarden frontman Chris Cornell announced Tuesday night he is cancelling his set due to "A scheduling conflict."
Cornell revealed Monday that he will perform Saturday at a huge Barack Obama campaign rally in Des Moines, IA. "Proud to support @BarackObama again in 2012. I'll be opening for him in Des Moines on Sat, Sept 1. Follow @OFA_IA for details. #fourmoreyears," he Tweeted Monday.
Surely, Cornell could play both locations on different days, what with planes, traines and automobiles to transport him from Iowa to Philadelphia. It is unclear if the Obama gig caused his Made in America cancellation.
