My Grandfather sang (to a tune similar to "the Hot Asphalt")

I'm just a common country boy
and I come from Donegal
When first I came to Belfast sure
I couldn't get work at all.
I searched around and up and down
and nearly was dismayed
Until at last I got an opening in
the scavenger's brigade.

Chorus:
We're always on our duty, boys
    In sunshine or in storm.
with our brooms upon our shoulders
    It's our only uniform.
In streets and squares you'll find us there
    we're always on parade
And we march in style, in the Indian file
    In the Scavenger's Brigade.

My mother writes to ask me
if my leave is coming soon
and she wonders if her darling
is a kiltie or dragoon
She asks about the hours I work,
the rates I'm geting paid
And if I'll soon become a sargeant
in the Scavenger's Brigade

I think there were more verses but that's all I can remember.

Does anyone know/remember it?
