From The Fiddler's Companion:

MOCCASIN TWO-STEP. American (?), Two-Step. From the playing of the late Joe Robichaud (d. 1999), a fiddler from northern New Hampshire who learned the tune from a trapper friend who claimed he acquired it from a Native American musician. The tune was untitled, so Robichaud invented "Moccasin Two-Step" for his version. Rounder Heritage Series 1166-11592-2, Oscar "Joe" Robichaud (et al) – "The Art of Traditional Fiddle" (2001).
