Travelling home from morris practice last night I turned the radio on to BBC Radio 5 where (at the start of the programme) they were discussing what was coming later. One of the topics to be covered was folk and they began by discussing what the presenter and guests defined as folk. As can be expected they came up with men in beards (but not moustaches), real ale, fingers super-glued to ears etc and wanted listeners to text or email their definitions. It then morphed into the handy phrase "Folk not Joke". Needless to say before any audience contributions were read out I, in a deep depression at what I knew was about to come, turned over to Radio 4.

Would it have been so hard for them to have someone that new about the subject as a guest?
