the version I have from the Battlefield Band has two extra verses that don't appear on the DT version. The first is at the beginning of the song:

I dreamed a dream the other night, a dream of long ago
I saw yen o' the travelling folk, along the open road
His step was light, his head held high
tae catch the scent o' spring
and his voice rang roun' the countryside, and he began tae sing

Then the song continues more or less like the DT version, but at the end there is this verse:

When I'd awoken from my dream, the dawn song had begun
The birds sang out their old old song, to greet the rising sun
I lay along the shadows and I thought of days long gone
And those wand'ring tramps and hawkin' lads
Whose days are surely done
