Once again Diane comes up with an original but argumentative idea.

What you're saying about pop tunes though - people used to say about folk. Someone like Owen Brannigan would do the Rocky Road to Dublin, they would say - oh wonderful, he's taken all the crudity from it - or Moira Anderson would do Ye banks and Braes - and they would say she's added refinement.

Someone like Bo Diddley can get more subtlety and genius from a E major chord that most people can get from a set of slip jigs. Its all down to the artist.

The content and structure is in a way irrelevant.
