Underground is also use in the first line of the next verse, knowing Peter's songwriting skills I doubt he would use the same word twice so close together, however I will check

next verse

He'd do odd jobs for one and all
though snow was thick or rain was teeming
and all the world would seem to call
the kettle never finished steaming
reach up! he'd say, by God you're looking thin
while mischief in his eyes were gleaming
if Lizzie thinks you're hungry still
there'll be nowt for us in her will

The day you left I stayed outside
scalding tears no comfort knowing
we all turned up to say goodbye
the church was filled to overflowing
you'd never have believe it if you'd seen
how many people mourned your going
and just how lucky folks still feel
to say they knew Joe Peel

repeat last 4 lines

I'd actually forgotten just how moving this song is ......
