Just like to add,, the shaky stand nor the audience, hampered Bartmans performance in anyway. He is a real professional and I'm sure Yamaha are very thankful to have such a talented person. He is the full package, exceptional musician, has the personality and humour to be a great clinician/demonstrator. He certainly showed it here.
My favourite tune was the last one he played "SkyFall" Super job!! By the way,,,where exactly is this place where he is performing?
