Incidentally, the 'Key Moments edition' that I thought was going to be on Spotify (but still can't find) is available as individual videos on YouTube - I haven't checked if they are all there yet, but it you search under 'Alison Moyet conversation' you'll find lots of them.
I decided to actually buy the digital album including it from webstore yesterday. Obviously this is focused very much on the individual tracks, and it's still with the same interviewer, but also includes the producer Sean McGhee, and I found it really quite interesting in places. Alison seems a lot more focused and less prone to some of the ramblings amd diversions in thr main podcast, as much as I'm still enjoying them.
