== Complex Key Changes? == 

 Except for the chorus, almost this entire song uses the chords D and Bm. I find it hard to believe that due to a tricky chorus (of a rather short duration) that Hell left the band because he simply couldn't play the song. I imagine more likely is the tension created when a populist sort of guy like Hell plays with a technical player like Verlaine, they both end up going their separate ways. To make a long story short, there needs to be some cited evidence that this is why Hell left.
