Yes, the US (Funimation?) version and original has different soundtracks, both for the opening and for in the show. I'm not sure which was used in other regions where the show was popular, my guess would be south/central America got the Funimation music.
While I've never heard of Dragonball--and I'm sure it's really great--I'll make a wild guess that 100s or 1000s of people worked on it in one capacity or another and that doesn't really make them "Notable".
That sounds great. I was actually thinking "video game" but didn't bother looking it up because it's not really that important, is it after all?
But I can think of some other musicians who've worked on cartoons--David Bowie, Roger Waters, Primus, uh, Art Garfunkel. One thing they have in common is their notability didn't really come from that type of work. Straining a bit through the mists of time, I suppose Frank Churchill is genuinely notable for his cartoon work. Matt and Trey, of course, but they are writing show tunes for fun, it seems.
I mean, it's incidental music, right? Hollywood has lots of people who do that. No one cares about them either.
Did he do the music for the US dub maybe?
