Interestingly enough Jack, that's "Story from a thin wall", which became "Berlin" on their next album, "Seasons end". You really should hear it, it's quite amazing how they changed the song and yet kept it the same.
I ran a feature on it in my "Run for cover!" section in the journal: have a look here

Have you listened to Fish's solo material? As it happens, the above song also used lyrics (but not melody) that ended up being in one of his own songs on his debut, one called "Family business".
