1980's.

If it was recorded by Ace Sewell in "1977?" (Voyager VRLP 319-S (1977?), cut #B.06), it's older than "early 1980's." This is the first recording I've found of the tune, and the Folk Index isn't sure of the date, but it seems more in order with Art's recollection. It was also recorded as "Ookpik Waltz," not "Eskimo Waltz," which was supposed to be the original name. I'm thinking maybe Ryan assumed it was written for a specific competition. Oy - the plot thickens...
