Well ignoring the rude person who comes from somewhere where six words constitute a thesis, I remember this song being played on Radio 2's 'Folkweave' program, hosted by Tony Capstick in the mid 70's.
The tune was indeed "In my Liverpool home" and the opening lines I recall were :

"Sweet Molly she was to be wed
To a chap from the village named Fred"

(then something about everything in place for the ceremony, best man/choir/ring etc)

"When somebody stepped up and said
If only the vicar were here
If only the vicar were here"

(Think there might have been a christening and funeral verse then the
last verse was along the lines of

"Old Nick he tolls the great bell
And calls all the sinners to hell

(ends lamenting that he's got all the vicars down here pretty much as the last verse already mentioned by Steve Shaw.

Hope this helps - sorry I can't remember more of it but it might jog a memory or two.
