'80s songs - one a day Watch
Ah, New Wave (Puddles - you can do your thing now!). I'm not quite sure what 'New Wave' actually means given that everything in the '80s that wasn't Rick Astley was referred to as 'New Wave'. Here, I'm going to differentiate this sub-genre from the bands that came before in this thread by referring to the 'nearly-mainstream' bands - they became well-known and charted, but were not straight-laced like Rick Astley (they had a bit of a twist, e.g., Gary Numan). I don't think the audience quite realise what greatness they are witnessing here.
I think the song is supposed to be about Antonio Gramsci, an Italian Marxist who was imprisoned by Mussolini (with his hammer and his popsicle, they put him in a hospital for good). I think the Jerusalem is referring to Blake’s Jerusalem in "England’s pleasant land". For further info, Green was a Marxist when he wrote this and the current thinking at the time was centred around Jacques Derrida, the French critic, French situationists and the writings of Gramsci.
No - it is a reference to a section early in Nietzche's 'Daybreak', when N. claims that early Christians were so disturbed that they had to build 'asylums in Jerusalem'. A fiction, I think. The song is either about these saints, or Nietzsche himself ... or both.
