Yes, to some of the negatives (breaking up numbers with interviews, etc) but what a refreshingly straightforward presentation after the previous 2 folk concerts on BBC4.
As for focusing on singers, it's always amusing to work out whether the cameraperson has any musical sense - isn't it great when you're watching something with a killer trombone or accordion or sax solo and the close-up goes on to the fingers of some guitarist in the front line who's strumming E?
