There are at least two songs called Widecombe Fair. There is a Steve Knightley one which has a very dark alternative take on the events. You will sometimes find that particular one spelled Widdecombe Fair, which isn't how Mr Knightley intended it to be spelled at all, but he missed the mistake at the proof-reading stage of the CD sleeve.

The Knightley song takes the trad song as its inspiration and was NOT intended to look like it might be be an ode to the looks of the Member of Parliament for Maidstone West...
