Oh, thank heavens! After Aerosmith's Steven Tyler told a reporter last week that he would embark on a solo career, and Joe Perry announced via Twitter his intentions to hire a new singer, the pair reunited last night in New York, ending the bitter feud that had torn their band apart for nearly six entire days. Tyler showed up unannounced at a Joe Perry solo concert at Irving Plaza and told an excited crowd, "I just want New York to know, I am not leaving Aerosmith!" before launching into "Walk This Way" to wild applause. Then, presumably, Tyler left and audience members listened contentedly to more songs by the Joe Perry Project. Video after the jump!
