Whoo hoo! It’s my new tutorial The Clarke Tinwhistle with cd! Yay!
Just in case anyone wants to know, the cheapest place I found to buy tutorials is Target. Really. Who knew?
When they start carrying O’Briain modified whitles at Walmart, then I’ll be happy. 
As it is, you still get a Walton Little Black D at the Celtic Shop in Rapid City.
