Just in case anyone cares, I just got an answer to this question. I really figured since no one seemed to be forthcoming with an answer that it must be a really obscure composer. But it would seem the composer was Buddy Baker and the lyrics were done by X Antencio. Wierd. I thought the only lyrics X had written were for GrimGrinning Ghosts.
You know now that it's been mentioned I feel so stupid. This is one of those things that I've heard a million times and just never picked up. At the very least I should have remembered Pirates! Heck he's even got a lyric themed window on Main St!
