It usually is Silas :)
The difference between this programme and the Transatlantic Sessions, along with many other Scottish music/TV progs is just this. People who perform, are more involved in the production and direction of many of our programmes, notably Rab Noakes. While people like Archie Fisher, and Mary Ann Kennedy actually present programmes.
They both still perform, and draw audiences, whereas I get the feeling that Mike Harding is now passé, and out of touch with what's happening around the clubs and festivals.
It looks to me, as an outsider, that the production and presentation of folk programmes on English national TV and radio, is a closed shop.
