Watching Disney Channel with Jake yesterday morning, and there was a trailer for Hunchback films I and II showing today on the Cinemagic channel. The Hunchback II film had been on before, and the only thing that I could remember about it was that it had a beautiful song in it, so I set it to record.
Looking at the recording now, I see that the song is called "I'm gonna love you" and its sung by Jennifer Love Hewitt. iTunes don't seem to have a copy in their store, but here is a Youtube music video of it.
