Well, I was willing to give the fiddler I saw a bit of leeway on his dating of the tune (600 years or so). He did a fine job on all the tunes - very old-timey sounding.

He was with a group out of California called the Black Irish band and he was pretty good. (Can't remember his name though, darn it!) He claimed to have won the old-time fiddle contest at Galax (Virginia) in 1993, and he sounded like he could have. It's just that I never thought of that tune (House of the Rising Sun) as being British, or Irish, but maybe the other one.
