I don't recall Groucho singing it in a particular film...(must have been the part I fell asleep), however, he did perform it on the premier of the first Bill Cosby Show in the mid to late 60's. I remember this as it was the first television performance of "Noah!"... I was sitting with my younger siblings and remember beingblown away by the tune and trying to remember the lyrics and write them in school the next day...
