Wow! I had no idea you could get Audacity for free. If anyone is audacious enough to learn how to play the aforementioned "Powerhouse" by Raymond Scott, I'd be truly amazed! Fun season ahead!
I got a book of Looney Tunes sheet music a few years ago. It has a few of the Raymond Scott tunes that Carl Stalling used in the Looney Tunes soundtracks, including Powerhouse. They are all just as hard to play as they sound. If I ever get one of them done, it will probably be Dinner Music for a Pack of Hungry Cannibals.
