I think I can pick out maybe three songs on Abacab I like or at least don't hate ("Dodo/Lurker", "Me and Sarah Jane" and "Like it or not") whereas there's nothing on "We can't dance" I don't like, so I would consider it a far superior album to "Abacrap" personally. Also, "Abacrap" was followed by the self-titled, which though it has "Illegal alien" (

) is a really decent album I feel.
I also love GtR: I think it's almost like their "Piper at the gates of dawn" or Supertramp's debut; shows a totally different side to the band with hints of what was to come in "Trespass".
