Youtube has a tune called "Country Waltz" :
Country Waltz - Old-Time American Fiddle Tune. This tune is on page 77 in The Fiddler's Fakebook - a source for many of the tunes I play. It's called Country Waltz - and is listed as American. The book lists this recording - 25 Old Tyme Fiddle Hits (K-Tel FH1).
