Well its not really hard to figure out what they would have sounded like in the short term. Trick of the Tail would have been almost exactly the same but maybe with "solsbury hill" and/or "moribund the burgermeister" on there. Wind and Wuthering is a bit more difficult to call, but I think we would have seen more of Steve Hacketts songs on there, cus PG often sided with him during disagreements. After that who knows, but I think that they would have ended up moving in a more commercial direction anyway.
