Hey Mike,
I just joined here a little over a week ago and want to say what an excellent teacher you are! Not a lot of great players can also teach what they do, but you are one of the rare ones that can do both well. Your song tutorials are so clear and exact - making it easy for us to know what's going on too.
In just over a week, I am now playing along with Touch of Grey and have about a quarter of the solo down. It's tough to find good Grateful Dead tutorials online so keep them coming! (did someone say Sugar Magnolia? Scarlet Begonias??)
