A track called Zorch was the B-side of a single called Captain Hideous, released by novelty artist Nervous Norvous in 1955. Norvous was heavily influemced by a radio comedian named Red Blanchard; the word “zorch” appears to have been coined on Blanchard's show in the early 1950s. The word itself had no meaning, but there where compounds using it that did — “zorch cow”, for example, was a variant of the Chicago-area slang “black cow” for a root beer float.
