Its one of my favourite songs, and has a pretty cool video - see Jon standing at the window? He has a fabulous butt.

But I dont know what the clip is about. Either she is a ghost or he is. At the start she is sitting near him and then at that club thing she walks right through him so I thought okay, she must be dead as he's remembering her. Then we see her from parts of the clip we have already seen and he is not there, giving me the impression that it is he who is gone and she's remembering him.

Or am I completely wrong in this? I'd really like to know what its about.
