A couple weeks ago I bought the Inside Llewyn Davis soundtrack on Amazon. It arrived a half-hour ago. The song lyrics are printed on a leaflet inside. Here, obviously, are the lyrics to “Please Mr. Kennedy,” the show-stopper performed at roughly the halfway mark. The authors are Ed Rush, George Cromarty, T Bone Burnett, Justin Timberlake and Joel and Ethan Coen. One of the things I hate about listening to karaoke (don’t get me started) is that the singers never seem to sing tunes with ironic attitudes. “Got a red-blooded wife with a healthy libido / you’ll lose her vote if you make her a widow.”
