The story I picked up over on Fiddle-L, that someone there got from the Fiddler's Companion, is that, according to Lawrence 'Teddy Boy' Houle, the tune was a combined effort of his father, Lawrence Flett, and Andy DeJarlis - an attempt in the morning to recall a tune they had constructed in the wee small hours, fueled by the energy drink commemorated in the title. The editors of the Fiddler's Companion apparently accept that provenance, for what that's worth.

For those who don't know: Andy DeJarlis was a prominent professional fiddler from Manitoba; he composed countless tunes, many of which are widely played - 'Poor Girl's Waltz' is one you'll hear all over Canada, at least. The fiddlers in the Ebb & Flow area of Manitoba old enough to have been around at the time claim DeJarlis learned everything he knew from the Ebb & Flow fiddlers, of whom Walter Flett was no doubt one of the best. Andy DeJarlis was apparently a frequent visitor to Ebb & Flow; I don't know if he had family there.

'Teddy Boy' Houle is a leading fiddler in the Manitoba Native tradition.
