Thank you. He also had an hour's session at the end with the more experienced students and I stayed on to see what that was all about. Basically he played and sang a more difficult song. The students had copies of the song and played along. There was a little bit of explanation but not much; it was really more of a demonstration though he did have the webcam on so you could see his hands. That particular evening is one that is really good for performing arts events - lots of good things clashing - so I wouldn't go to his classes indefinitely, just for long enough to improve from where I am. I would like to make my own arrangements eventually.
