I love it. I love seeing anyone as fanatical about Genesis/PG as me. I hit upon them around 1982 or 1983, when I was about 15 myself.
Naturally, I've seen The Musical Box about 4 or 5 times, now, including "Lamb" twice. The first time for Lamb it was pretty much perfect, but the most recent time here in Boston, his mic wasn't up at all for the whole quiet intro of "In the Cage" --- causing all of us to joke that "well, that's probably what it was like in '75!".
If only someone could really do a proper restoration of the concert film.
Anyway, I'm not one for religion but GOD BLESS YOU for your wonderfully detailed work and playful hosting. I'm very impressed!
