Getting even further off topic, but... yes, that sense isn't something you really get on Genesis albums, is it? The (original) ending of "Anything She Does" is the only thing I can think of that even comes close. (In contrast, another favorite band of mine -- pre-1980s Chicago -- has quite of bit of that on various albums.)
When I remixed Abacab, I used as many of the count-ins from the bootleg of that album as were available. That kind of element wouldn't really fit their earlier music but certainly when they had their own studio, where everything sounded so fresh because it was put down on tape immediately, it fits perfectly.
I love the "agh!" at the end of Anything She Does. When Mike was interviewed about the album some years ago as part of Radio One's Classic Albums series, he said that the song had quite an organic feel to it which was why they included that at the end. Of course, Phil's done stuff like that a few times - at the end of Somewhere Over The Rainbow on Face Value we hear him say "okay" and then at the end of You've Been In Love (That Little Bit Too Long) he can be heard quoting Ringo's "I've got blisters on my fingers!". He also can be heard saying something at the end of We're Sons Of Our Fathers but I can't remember what it is.
