I don't have the music to Barrow Boy but here are the words - minus correct punctuation and possibly proper formatting. As I've heard it, the song repeats twice (or is that redundant? Repeats once? Oh sing it all the way through and then sing it again!)

Reen

All me life I wanted to be a barrow boy
A barrow boy I always wanted to be
I wheels me barrow
I pushes it with pride
I'm a coster! A coster!
From over the Lambeth side.

I turns me back upon society
Take me where the ripe bananas grow
They're only a dozen a shilling
That's how I gets me living.
I ought to have been a barrow boy years ago.
