This is what we sang as a campfire song in the Boy Scouts 70 years ago:

"All me life I wanted to be a barrer boy
A barrer boy I always wanted to be.
I pushes me barrer I pushes it with pride I'm a coster, a coster,
From over the other side.
I turned me back against society down where the ripe tomatoes grow.
I sells em for a shilling
That's ow I earn me living
I oughtera been a barrer boy years ago
--Git off me barrer --
I oughtera been a barrer boy years ago"

The toff accent and cockey accent don't quite mix, but...
