Paul Richards (of the California Guitar Trio) has uploaded some video footage of the boys in action at the NAMM convention in LA, January 2005.
The audience are clearly enjoying this rendition of that Yes classic, Heart Of The Sunrise with our very own Tony Levin guesting on bass.
Then things really take off when out walks special guest, Jon Anderson, to do the vocals. Paul tells me the punters at this gig had no idea Anderson was about to appear.
