All I can tell you is that I read Peter Gabriel's biography, and nowhere when he spoke about
The Lamb did he refer to it as a rock opera. And he wrote the damn thing.
Anyway I thought you wanted to drop this? Throwing a load of links at me after I've said **** it do what you want is a little like kicking someone when they're down, is it not? Stuff your links. I grew up with that album and nobody I know has ever called it a rock opera. But, you know, you do you and I'll do me.
