In perhaps the only time we'll ever tag a post "Rod Stewart" here on PMA - someone prove us wrong? - tourmates and songwriting buddiesBeck and Jenny Lewis pulled an Arcade Fire and joined forces for a cover of Rod's classic "Do Ya Think I'm Sexy?" during a show in Seattle last week. You can watch some good-quality fan-shot video of the event below; it sees Beck and Jenny trading off verses and teaming up for that inimitable chorus. Check it out.
