tradional musicians, do not have to move around,to be influenced by the outside world,Jamesie Kingston Traditional Fiddler, lived five miles from me,and only had a wireless,but would learn tunes [jimmy shand]etc from the wireless,he would also learn tunes from a revival musician,like myself.
HE had in his repertoire Dashing along with the smoothing iron,he had learnt this from an english revivalist 20 years earlier,who had been on holiday in the area.
no traditional musician /singer is an island unto himself.
