Here's the video of Steven Tyler, on stage with Joe Perry, claiming he's not leavi

Steven Tyler made a surprise appearance at a New York club show for Joe Perry's side project. Before blasting into Walk This Way, Tyler told the crowd "I just want New York to know, I am not leaving Aerosmith. And Joe Perry, you are a man of many colors but I, motherfucker, am the rainbow!"

Perry sort of mumbled something that slightly sounded like "you're an asshole."
