My Chemical Romance brought out surprise guest Billy Corgan to perform “Bullet With Butterfly Wings” during their concert Friday in the Smashing Pumpkins’ native Chicago. I never felt anything like that in my life.”My Chemical Romance welcomed “Bullet With Butterfly Wings” into their Long Live the Black Parade Tour setlist over the past month, performing the track a couple times perhaps as a precursor to Friday night’s collaboration. It is the best rock n’ roll song ever fucking made,” Way added Friday. Corgan then joined My Chemical Romance onstage to perform the Mellon Collie hit. And fantastic gig by the boys,” Corgan wrote on social media after the show.
