Swift, flowing, sweet major-key verses become roiling minor-key choruses with ease. The many voices and instruments of the band add their measure to a thick fabric.
My favorite part is the middle bridge, with a great drop in dynamics and wonderful vocal rhythms, until the vocals hold on a long crescendo that refuses to resolve, then finally veers into a chorus with an awkwardly near-interval chord change.
The lyrics are vague except for a cool reference to the old Bob Dylan concert film Don't Look Back. The album to which this song belongs - If You're Feeling Sinister - is full of portraits of characters defined by varying forms of inner sin and redemption.
Such a charming, excellent song.
