Black Diamond is a far superior song to Rock And Roll All Nite... but it's a terrible set closer. They closed with it at Sweden Rock and because of the way that song ends it just goes flat when everyone should be euphoric.
They should start closing with God Gave Rock And Roll To You II, instead of using it as the outro tape.
