How about a Danny Gill Mississippi Queen lesson? Surprised it hasn't been done yet. It's a classic, I mean who doesn't like Mississippi Queen? I think it would also be a good one for beginners to get going on but would still appeal to more experienced players as well. Pretty easy to make noise that sounds like Mississippi Queen, not so easy to get up into the awsome zone of the cool meter. I'm gonna feel pretty dumb you guys already did it...........where do I buy it?
