Now I know he just does it just to annoy. On the influence of the Carter Family in today's Herald:
Without them, for example, Bob Dylan would not have been able to plagarise his "boots of Spanish leather" line (he took it from the Carter Family's Black Jack Davey.)
It's shoes anyway, in that song, not boots and it is a traditional song not written by A.P or any other Carter. Get over it, dude.
