What the heck is the origin for the name "Twang"?!?

[Zaphod77]

Every place i've ever seen this song officially titled, it's been 'Ten Lemmings" (and if 1 lil Lemming, should accidentally fall...) or TenLem when there's not enough space.

Methinks this song could use some lyrics... anyone up to the task? (all ten of the lemmings should be dead at the end)

Which version has the word twang applied to this song? Is it the internal title for the .mod file?
