f they played nothing from it on the last few tours, that does not necessarily mean the band shared your dismissive opinon of it. .
No, of course it doesn't necessarily mean that, it might though, it's not something you can discard.
I'm sure there are songs, from other albums, they are not particularly keen on they feel they have to play, for whatever reason but ultimately the fact that Abacab was dropped entirely and consistently probably means something, doesn't it? Whether it's because the band don't stand behind it anymore or they feel the majority of the fans are not crazy about it I really don't know but it's telling. And yes, I am dismissive of it, respectfully but dismissive, I don't think it's a strong album and I don't believe Genesis will be remembered by it.
