This video is a little shaky, but it's worth hanging in the amateur videography for the classic moments following: Lady Gaga, Bruce Springsteen, Elton John, Shirley Bussey, Debbie Herry and Sting sing "Don't Stop Believin" at Carnegie Hall. If you ever wondered if the classic Journey song is the best karaoke song of all time, or if it's mandatory to make that face while holding the long notes, you can bet your Lady Gaga fist pump that it is. Here's the backstory: the celebrities were assembled for a Rainforest Fund benefit. I discovered the video via The Awl blog. What's your take on the video? Would you win a karaoke challenge against this crew?
