I also enjoyed this chapter, even though I was unfamiliar with the radio drama until now. For those of you who, like me, haven't had the good fortune to hear it before, they appear to have all the episodes
here on YouTube.
I've now listened to some of the radio drama, and it's interesting to do so after reading Smith's essay, as I find myself being particularly attentive to the music. So far I find Oliver's settings of the songs to sound very "authentic" - by which, I suppose, I mean that they sound very much as I have always imagined them to.
