Counting Out Time

I've no idea if anyone is familiar with 'The Lamb Lies Down On Broadway' by Genesis but I've had this particular track in my head for days now.

Music gets me like that....I don't hear something for months even years but when I do, it'll be with me for over a week... even when I'm meant to be sleeping!!
The frustrating thing is, it's my least favourite track from the whole double album.
