A few months ago I read in the Pueblo Chieftain that Elmer Swartwood passed away at the age of 87 (December 3, 1924 - July 17, 2012). Elmer was the founder of the Prairie Hornets, a local Pueblo country and western and square dance music band.
Somewhere along the way Elmer teamed up with caller/singer Al Horn, and his Prairie Recording label, out of Denver. The partnership resulted in several recordings for the group, including "Mr. In-Between" (PR 1004), "For He's a Jolly Good Fellow" (PR 1009), and "Coon Dog" / "Square Chords" (PR 2001), among others.
Al went on to be a pretty prolific caller, recording almost 100 singles for the Desert, Mountain, and Ocean labels, and later a Hillbilly bopper on the Do-Ra-Me label, "Where Does Love Go" / "It's Much Too Soon" (1424).
