Just heard from someone that he used to dance western swing to the song "Sugar Shack," which came out in 1963. Here's a couple of fast forward bonuses - an item from 1976... Jazz fiddler Joe Venuti has recorded an album for Flying Fish Records that high-lights the close ties between swing jazz and the “western swing” country music tradition. Can't figure if the album, or cuts from it , was ever released. And... I have found a 1980 ad for West Coast Swing as a Cowboy Dance. Go figure.
