During a live concert at the Portland Zoo in Portland, Oregon this past Friday (July 18), Tori Amos performed a live piano mash-up, interweaving the lyrics of Aerosmith‘s “Dream On” and Ms. Grey‘s I Need A Doctor hook!

A fan taped the 6-minute live performance, which you may watch below – also check out a photo of the full setlist (photo via Tori Amos‘ Facebook).
