The piano in FF3 (j)

I think I recognize some of the songs played ón the pianoes (that's how ya spell it?) in FF3(j), but what about the longer song (with a bunch of people dancing to it)? Is it a real song or an idea by the wonderfull composer?

I've looked long and hard for the identity of that song.

So far, my best guess is "Travellin' Band". But I only recognize the refrain. So *shrug*.

Shouldn't this be in the music section.
