A fiddler and Facebook friend from Central New York near Utica, Jim Stanko, this afternoon sent me an mp3 of his fiddling of this wonderful tune, "Double File." He does an outstanding job on the tune, and subsequently I added clawhammer banjo, bass, and guitar to the fiddle. The result of the mix is the tune you're hearing here.
Source Material from The Fiddler's Companion: DOUBLE FILE. Old‑Time, Breakdown. USA, North Carolina. A Major. AEae tuning. AABB. The tune "bears an obvious resemblance" to the commonly found "Leather Breeches," says Bill Hicks (1972), who also sees similarities to Emory Bailey and Burl Hammonds version of "Camp Chase."
