Not a lot of listening time in the last week, I decided to compare three different sets of Under Milk Wood. Just one cover so there is a picture, two copies of the BBC version, both numbered RG21 and RG22. Two separate discs in the cover shown, clearly labelled mono. The same numbered discs in a gatefold sleeve, which sounds the same. Then the Caedmon recording of Dylan Thomas in New York, definitely no high to the fi, there is a definite sense of acoustic/atmosphere.
