M-G-M's Leo the Lion does four extremely short, quick roars, one for each kitten, to the Tiger Rag (aka, "Hold that Tiger"). This rare event occurred only twice, in this short and Blitz Wolf (1942). Only 3 weeks separate their release dates: Tex Avery's Wolf was first, on Saturday, August 22, 1942; this short by Rudolf Ising followed on Saturday, September 12, 1942.
