Last January we saw Sam Beam perform "Flightless Bird, American Mouth" by his lonesome. A year later, he's reprising The Shepherd's Dog closer on Leno with band in tow. If you haven't seen Twilight it might seem strange that he's making the Late Night rounds for an album that came out in the Fall of 2007, but beyond teenage vampire movies, the song's take on the loss of innocence/an idealized America, materialism and fat cats devouring flightless birds is all the more chilling amid the dust of our fucked economy and feels like the better reason to be singing this particular song. You can watch it at Hulu.
