A friend of mine lives close to Harcourt Park, and he says he also heard Dwarfes singing there. He wasn’t quite sure what is was that they were singing but says he recalls the lines:
“Dwarfes we are, brave and bold,
we swing our axes and search for gold”
This is all I know I’m afraid,
I hope it can be of some interest.
Not to sure about the lyrics, but you never know…
