I had a look at a whole lot of versions of the song on the net earlier. Hardly anyone gives croft at the end of the 1st line. Most common variations were wall, cry, door and in one I think croft fall (to rhyme with the 3rd line I suppose).

The Salford wind was rendered usually as smokey/smoke-filled and sulphured (this latter in Rod Stewart's version).

And at least one had a note something like I learned this song in Dublin, the "dirty old town"

I think ho-hum covers it.
