Oh Wow! I love guys with a super positive attitude! It is.... Inspiring! Isn't it Def Lepard that has a single arm drummer as well? I'm not sure, but I think he played without prosthetics and play a lot of double-base.
My son, a self-proclaimed ball python expert, age 5, has been taking drum lessons for a year now. He has a practice pad, a snare, and bells (looks like a xylophone but they call it bells for some reason). He plays whatever is the assignment for that week. The teacher is awesome! He was the only one that was willing to take in a persistent, rumbunctious 4-yr-old.
