It’s been a few weeks since Carl & Christy’s got hitched, so the New Pornographers had ample time to rest up after the NP nuptials and bring Challengers to Letterman’s live studio audience last night. There’s a Neko but no Destroyer (not with them on this NYC trip — sorry Bowery Ballroom — choosing to join for the Pornos’ jaunt through the city for October’s Webster Hall shows instead). Watch Mr. Newman’s picking hand after the pick-up, rocking that power-pop shuffle. And while you’re keyed in on Carl, note the downward cast eyes. And the piece of paper on the ground in front of him. Lyrics sheet? Maybe it wasn’t ample time to rest up post-wedding after all! Anyway Carl, forget paper — do it Axl style.
