What song is this? From end of "Four West Coast Seeds in August"
 

So there was this DoD track that I didn't really care for, but at the end they have this neat part that sounds like a real VGM track, though I don't know what it is or where it came from.

Here's the tune in question.

And here's info about the DoD track:

"Four West Coast Seeds in August"
by The Slack Jawed Yokels
Dwelling of Duels: August 2006 (Free Month)
Castlevania 3 Arrangement

Anybody have a lead on where this mystery tune comes from?
