Probably the best parodists of English traditional folk music were the Kipper Family, now reduced to young Sid.

Their extensive research into the bye-ways of folk songs revealed such gems as "Biker Bill and Walter Shaw" (jollier lads you never saw) and a whaling song starting:

'Twas in the year of sixty-four (or was it sixty-three?)
We set sail from Solihull bound for Amerikee.
The winds they were a-roaring. it was a fearful sight.
It took us forty days, me lads, to reach the Isle of Wight.

... continuing in the same vein ...

The captain's name was Gladys. He wore a dress of red,
Which maybe was the reason he was not marry-ed.

...It was his pride and joy
To take a turn around the deck with the handsome cabin boy.

...etc...
I don't know whether any of Sid's songs are on the Net - anybody know?
