I see the confusion over Don MacLean's pub got cleared up before I arrived. I recall Don performing trad songs in early days, Dougie still does. In Scotland nowadays the terms folk and folksinger are totally devalued. They denote a pub with a Corries imitating guitar thrasher in the corner yelling songs into a mike with no regard to the meaning of the words, let alone any subtlety. Folk is music to talk over and get drunk to. We talk about traditional music and song just now - the terms are often misapplied, and will in time become devalued too, but not yet.
