I wrote this as a parody for 1 piano 4 hands. I got the idea from hearing children at my church playing the main theme almost every week at the piano. I wanted it to be fun and exciting, technically challenging for the players, and for the listeners to enjoy the different familiar melodies incorporated in the music.
And about the key of G-flat, it is a very playable key. If I can play it then other advanced pianists can pull it off. Don't let the looks fool you.
p.s. I revised the middle section and the weak ending to the suggested stronger ending.
