To be pedantic about Baz's and Guest's verses 2 and 3, the versions I learnt from when my dad used to sing it in Cornish pubs were:

White stockans, white stockans she wore
White stockans, white stockans she wore
White stockans she wore
The same as before
Goin' up Camborne 'll, comin' down

I knawed 'er old father, old man
I knawed 'er old father, old man
I knawed 'er old man
He blawed in the band
Goin' up Camborne 'll, comin' down

The third verse "I 'ad her..." is often politely left out in "family" situations.
