Hi Mike: I just wanted to say I am really enjoying working through this lesson. I have finally got it in my head and playing by memory. Now it’s just getting all the timing right (measure 21!). After many woes I picked up the reverse forward roll when shining up the joy to the World lesson. It’s a great little lick I don’t see that often elsewhere and works so well in this song and many others. Thanks for the great arrangement. Best, Mike.
