More observant YouTubers may have already noticed this, but when you watch this trailer for the Coen Brothers' "Burn After Reading," on the YouTube site, a link pops up when Elbow's "Grounds for Divorce," starts playing. The link says "Click Here For This Song," and it takes you to a performance video. Ditto Spirit's "I Got a Line On You."(It doesn't seem to work when a vid is embedded so to see it in action, go here)
Word of caution: This trailer is the "red band trailer," intended only for mature audiences, such as yourself.
