Here a great shot from 1919 — a goat doing the shimmy to ukulele music (from the New York Tribune, 14 September 1919).
The caption reads:
‘Now that the Dancing Masters’ Association has put the taboo on the shimmy, Geraldine Rays, of Los Angeles, is at a loss to know what to do with her pet goat. He’s the original Shimmy Kid, and just can’t make his feet behave when his mistress plays, “Oh, Minnie” on the ukelele.’
My attempts so far to identify the tune, “Oh, Minnie” have led me to “Minnie the Moocher” (too late), Minnie Bannister of Goon Show fame (too silly), and Minnie Mouse (too silly and too late) — my search continues.
