I know this doesn't respond to the question, but FWIW, Filthy McNasty was the name of a character in the W.C. Fields movie, The Bank Dick. According to the Wikipedia article on Fields:

" 'Filthy McNasty,' the villainous bank robber from The Bank Dick, inspired jazz pianist Horace Silver's composition of the same name, introduced on his 1961 Blue Note LP Doin' the Thing: The Horace Silver Quintet at the Village Gate. According to Silver (quoted by Herb Wong in the liner notes for The Best of Horace Silver) the classic Fields film was playing on television while Silver was inspired to compose the tune."
