I did manage to get the answer to the leaking mouthpiece. The clamp that holds the reed in place on the mouthpiece was not tightening. When George blew into his mouthpiece the reed didn't have a tight seal and thus it would just product air. That is the leaking mouthpiece.
Wouldn't it be better to have a mouthpiece where the clamp is all one piece? The only reason I can see why not wouId be changing reeds on the fly during a tune may not be as easy as the clamp being separate component.
