i just bought parking lot etudes. Electric Wheelchairs music is a little odd in the begining. If you listen to the recording their are 3 rolls in the beginging. The music in the book has 2 rolls. Now that i mention it, the first 4 measures or so are very different to any version i have ever heard. If i sound like a jerk sorry. I LOVE THE BOOK ITS GREAT. Anyone who writes for SCV is a precious gift to :D our world. thank god for you all.
