A tune that is played at one of my local sessions, set with another tune entitled: "The Mudgee Schottische".
The guy who plays the set learned the tune from an LP entitled: "Bees on Horseback", which was recorded by the Flowers and Frolics Band on the Free Reed label in 1977.
I gather that this tune (along with the Mudgee Schottische) is of Australian origin.
For speculation about the origins of Mudgee Schottische, see
Indeed, fen …
And it could also be that "Whistling Prince" (although of Australian origin, as posted), is possibly derived from an Irish, Scotiish or English tune taken there by the early settlers.
It’s a funny old world … the only Aussie musicians I know who play the Whistling Prince learnt it from the Flowers & Frolics recording!
