Lemmings - Unknown

So far, I have yet to hear a midi, mod, or any other type of file made 
for this song. I also have no idea
what famous piece of music it's based on(since most(most,
not all) of the music in this game is loosely based
on existing pieces of music). But seeing as how it's
a neat song, and I'm sure there are tons of Lemmings 
fans out there who are familiar with it, I've tabbed it 
anyway. For clarity's sake, it's level 1 on the 'tricky' 
setting, in the SNES and Amiga versions of the game.
