Before you ask, yes, I have tried the forum and it won't produce the goods for me!

I am seeking origins and further info about a song which goes:

"Oh I am a merry-hearted drover boy, I'm a herder brave and free,
For my days are passing in a round of joy and there's none so blythe as me"

It's not Australian to the best of my knowledge in case you were wondering: in fact what words I have are in a similar vein to the above and sound to be rather formal English.
