Your version differs little from a version recorded by the late A. L. Lloyd on Prestige/ International 13066. In verse 4, "Not thinking..."

Lloyd has a final verse:

Come all ye young gals wherever that you be.
Beware of them colliers who are single and free,
For their hearts do run light and their minds do run young,
So look out for the fellows with the pit boots on.

Lloyd's notes say the song is widespread, and his version came from Durham miners. I have half of a recollection of seeing a version with 'with his Navvy boots on', or 'with his apron on'.
