Folklore sounds about right. Otherwise - 1954? Don't believe a word of it! Folk is just another style of music; a whole bunch of styles actually. As for Folk Arts, well that's a made-up term as well. All Arts are Folk Arts - I ain't never seen no horse pimp a ride / knit a jumper / tell a story / throw a pot / make a macrame owl / carve a love spoon / make a set of Northumbrian smallpipes / decorate a Christmas Tree / break dance / morris dance / do a Cubist still-life / get a tattoo / crochet a tea-cosy / get crafty with bendy straws etc etc.
