I should expand on that thought. My singing partner wanted to learn "The Cocks are Crowing" after hearing it at a resort show and buying the show's CD. Not knowing it myself I searched the internet and found what I guess is more or less a traditional version with at least twice as many verses as the show. They would have been lost to us if relying on the commercial version.

Of topic - when searching for Cocks are Crowing the ever-helpful Google asked "did you mean to search for cows are crowing"? Later I searched for "midi Cocks are Crowing" so Google offered "mini cows are crowing".
