Brian's description of Harker's take on the Radio Ballads is accurate - except that Harker clearly DOES think they were great regardless - not as big a step forward as we might have liked, but a big step considering the historical circumstances.

However, his treatment of Parker really is inadequate. You get practically no biographical detail, and the way he got dumped by the Beeb for standing by his principles should have been described - it was surely relevant to the story Harker was telling.
