Steven Tyler made an appearance last night on Jimmy Fallon to talk about his new position as an American idol judge. Now how is that interesting some of you may be asking yourselves?! Jimmy then got Steven to blast out a rendition of Aerosmith's smash "Walk This Way" in which Fallon himself guested. I know Jimmy likes to get involved in performances with his guests from previous performances. If you missed the show catch another glimpse up at the top and get your groove on like it's 1977 again. Go thank the Audio Perv for the video.
