well it depends on the size of the ego eh, al, not everything is black and white there are shades of grey, however it does not alter the fact that revival performers are not necessarily the best people to discuss the roots of the music, there are exceptions like Carthy, folk scholars may be better qualified.
Seth lakeman and his producer have done a job that has flaws but could have been worse but some of the statements on the programme expose a lack of knowledge of the roots of the music.
