Well I saw most of the Christmas thing, and I was apalled. WTF were some members of the audience wearing? It looked like the Good Old Days meets, Down and Out in London and Paris.
If I had stumbled into this as a non folkie, I would have either quickly switched channels, or poured myself a larger drink!
As has been said, the Unthanks were good-ish, but badly miked up, the two lads on piano accordion and fiddle, looked out of their depth, but made a half decent job, apart from the self conscious MC work of one of them.
Bellowhead were their usual, sort of a cross between Spike Jones, and Black Dyke Mills brass band.
The programme that followed was very interesting, albeit, some of the clips shown, particularly Martin Carthy and Peggy Seeger, didn't look like they fitted the 50' and 60's parameters, the show was supposed to fit.
Both Martin, and Paul Brady, look younger now than they did in their respective clips :)
