Patsy Seddon (the harpist) did her postgraduate thesis on the early days of Gaelic broadcasting in Scotland, you might ask her about the musical content of it. (Though she might have long since blanked it out of her mind, I talked to her about when she was doing it and it wasn't a fun experience).

In Scotland, Radio Scotland (part of the BBC) has always been the most important broadcaster of traditional music, with the rest nowhere. The private broadcasters (both local radio and national TV) have always been utterly hostile to it.

The weekly Scottish dance music programme "Take the Floor" is probably the longest-running folk music broadcast series in the world - it goes back (albeit with a change of name, but not much in format) to the 1930s. Robbie Shepherd (the current presenter) would probably be happy to talk about it.
