Rugby league or rugby union?

Two inning matches, one day or 20/20?

The London Philharmonic Orchestra with a Vaughan Williams collection or John Connolly singing his Fiddler's Green?

Joan Baez singing Geordie or U2 playing Bloody Sunday?

Elvis Costello singing Veronica at a punk venue or singing Veronica when he supported MacColl and Seeger?

Sadly, nobody has the copyright on the word folk any more than the word music. 1954 was a year when a lot happened but nothing of note in committees set up to analyse music. Many pop, rock, blues etc songs relate a moment in time or reflect a community and its people. Many traditional songs are about the same.

Shagging, unrequited shagging and dying from cannonball wishing you were shagging.

We call it song, regardless.
