Not many "large scale" groups of youth doing folk/trad... but there are always some. Even during the folk scare of the 60s the young one were not totally into it. I doubt that all of them were into it when it was REAL folk...before recordings and collectors.

My son and his GF are in two different groups doing semi-trad stuff.... not exactly as *I* would do it, but they at least know what the sources are... (I am...umm.. helping... their education by showing them options, and they often choose the 'folkier' version.)
