"More Fool Me" and "After the Ordeal" aren't great songs, and the album would probably work without them. (It would even still be a fairly long album.) But they do make for nice breathers between the long, epic numbers. ATO, in particular, strikes me as being a perfect follow up to "Epping Forest," both in mood and in title.
Before I heard the album, I kind of expected "More Fool Me (Vocals Phil)" -- as it was listed on the cover -- to be more of a full-band piece. Actually, when it comes down to it, neither of Phil's full lead vocals in the Gabriel era are really "Genesis" songs; they're both just Phil and a guitar player.
