Here's an old tune called "Love Vigilantes" by an old favorite band of mine, New Order:
Here's that same tune covered by Sam Beam of Iron & Wine. He played this last week at the solo show I saw with some friends up in Chicago. It was a great night, and this was one of the best songs of the set.
(update: apparently, they just played the tune on Fallon's late night show--I'll put it up here too)
