The whole song is about drug addiction, if you read into it in a different perspective and think about Oli doing drugs then they both connect perfectly. The line 'The skies were once paved with gold, now they rain on us all' is on about drugs, where your high on whatever everything seems better and more chilled out, but then the comedown kicks in and you come back to relality with a kick in the teeth haha, sooo 'Now they rain on us all' is just talking about the comedown and how you feel worse than you did to start with. 'Curtain close, take a bow, think we fooled all of them now' is refering to the fact about hiding being a drug addict, because if you fool people that your not an addict then you can do it without worrying. And to the 'Just like the living dead' bits and so on that's just being about being addicted and needing bigger dosses of it to get you high.
