Vicky Jenson, co-director of Shrek and Shark Tale had worked with me on several TV series. While she was doing storyboards on Taz-mania, she was taking piano lessons. I had been dying to find a piano teacher to help me with the 3rd movement of the Moonlight Sonata. So I phoned her teacher, Chris Nelson. He said he didn't teach classical, but that he was a composer and asked if he could send me some samples of his work.
We stayed in contact and did some music together. A year later, Vicky was producing the series Beethoven and she had asked me to do character designs.
Chris was trying to break in to writing music for TV. He put together some cues on spec and asked if I would write a theme song with him. So we put the song together, and Universal bought it! That simple!
