Let me try that again.

There was an incident supposedly at Bolton-On-Dearne I believe when the miners built a snowman which was an effigy of a policeman and Chief Inspector Nesbitt ordered them to knock it down.

They refused the order, so he knocked it down himself by driving a police car at it - but it had been built around a concrete post.

A song came out of this of which this is the only snatch I know:

"The miners built a snowman and Nesbitt knocked it down" X 3
to the tune ff "Glory Hallelujah".

Whether the story is true, and indeed the whether the song came out of the actual incident I have no way of knowing.
