Today's trip to the reel-to-reel zone in the basement results in a pair of tapes featuring vintage radio jingles, and an offbeat set of PSA's for The Missouri School for the Blind. The accompanying letter (found in the box and sadly, undated) states that they are "professionally done, and cover a wide range of information and mood; all the way from the light and humorous to the more serious."
An ancient Scotch Brand 4" reel box was found to contain the following short reel, which features eight rather magical jingles for a radio station which existed once upon a time, in Sioux Falls, SD, KISD. There is still a radio station in that general area with those call letters, but it is in Minnesota, and apparently began broadcasting as KISD in the 1980's, long after these jingles were recorded:
As wonderful as those KISD jingles are, the following series of extremely short jingles for another station, WEZV, Bethlehem / Allentown, also undated, go at least as far in the other direction, into unpleasantness, to me - garish and ugly, loud and obnoxious. This station has apparently been known as WZZO since the late 1970's, so presumably, these jingles date - 51 of them in just over five minutes! - from some time shortly before that changeover.
