I listened to some of these broadcasts when they were first aired. Fascinating.
I love these Internet "listen again" features because (unlike TV with its video recorders) there's no way to hear radio programmes if you can't manage to listen them when they're first aired - unless the broadcasters themselves repeat them or you can persuade a friend to record them on tape for you.
Well, there might be, but not unless you have expensive equipment .
