This ace ace tune starts with what might be a sample of film dialogue, wondering what it might be. Something like "We had everything we need - you, me, the snowman - Fu ck the snowman! We were ready to die for you" (sorry I don't have the track to hand to check it)
Might it be from The Falcon and the Snowman, which I've not seen?
Incidentally this song alone shows that Arcade Fire aren't nearly as original as a lot of people seem to think they are
