I think the interview with Karl Dallas mentioned above is perhaps the one you can listen to online via the British Library Reg Hall collection. The sound quality is not good. I have alluded to this, so it is not true to say it hasn't been touched on, it is the one where he talks about 'bawdy' songs. I think I have referred to it several times. But if Jim is referring to some other Karl Dallas piece then of course it would be interesting to listen.
