At school, I learned the Kookaburra song. We sang it so many times as a canon that I still remember the text.
I always sang the song like this:
Kookaburra sits in the old gum tree
Marry, marry me king of the bush is he
Laugh kookaburra, laugh
Kookaburra gay your love must be
Why I would ask the Kookaburra to “marry me” and why his love was gay was not in question.
