Ann and Nancy Wilson's cover of Led Zeppelin's Stairway to Heaven. I think this is really worth watching! Skip to 6m44s. There is a Led Zeppelin tribute show at the Opera House in about 2 weeks for anyone interested. It is why I have been watching LZ videos. Also check out Ann and Nancy Wilson's cover of Gimme Shelter with Queensryche if you haven't heard it. That was one of the songs that got me into metal. I heard Gimme Shelter in the movie Air America and googled (perhaps AltaVistaed) it.
