This being Voncken, and presumably an officially sanctioned Yamaha demonstration, wouldn't Yamaha have had a 'no cameras, no recorders' policy on the door. That's the trouble now, every Tom, Dick and Harry is sporting a cell phone and allows for this crap to go worldwide. I don't doubt Voncken's abilities for one second, but this sort of exposure doesn't do Yamaha any favours, unless you subscribe to the 'any publicity is good publicity' theory.
