I've listened to all of the episodes, some multiple times. Of course, being the prog dork that I am, the ELP, Yes and Procol Harum episodes were ones I knew that I had to listen to, simply because they cover albums I really love; I did learn of the existence of this album when I read The War of the Worlds in high school, but it didn't quite catch on with me mostly because I didn't like the idea of mixing rock operas with disco stylistics, and I just never made it past the first track.

Fourteen years later, based on your walkthrough of it, I absolutely will have to listen to it now, from start to finish. As Phil mentions, this is an album that is essential to pay very close attention to (if you decide not to dance to it), and back then I just didn't comply. I knew nothing about how this album was made in the first place, and even less about how it cleverly intertwines musical themes to provide a leitmotif-based and endearing retelling of the story. To paraphrase you, John, all four of you absolutely crushed it! Just a beautifully well done and unintrusive commentary track to an album that is, at the very least, really interesting and groovy, and I can't imagine that a listener will come away from this episode feeling at least a little enlightened.

I'll have to listen closer, but I think I caught a quote of a four-note motif from "The Augurs of Spring" during "Horsell Common" as well as the last moments of "The Epilogue (Part 2)"? Probably doesn't mean anything, though.
