Wilfred - the expression "Theer's nowt so queer as folk" is an old one used in Yorkshire (I don't know if anyone else in Northern England will also try to claim it). The phrase translates literally as - there is nothing as strange as the way people behave. It is one which has been used by well known public figures, and so has become known to the rest of the country.

The TV series using part of the saying was, quite frankly total crap and simply an excuse for gratuitous scenes. The story seemed to be only about homosexual blokes having casual sex at night clubs. Not a good image of the "gay" community to broadcast - no long term partners or stable relationships, just a set of totally iresponsible unpleasant people.

You will find nothing about folk music in it. It certainly is not about the old saying which has nothing to do with any form of sexuality.

Quack!
