Jon Huntsman was in a band! Yeah! A big hair, wailing guitar, "eff da man" garage band! Huntsman appeared on Letterman last night and feigned discomfort when David pulled out a photo of the presidential hopeful glaring under a mane of tangled locks among his bandmates. Jon eventually got himself up to the task of playing some hotel lobby standards (You know, jazzy chord progressions and glissandos), and it was all pretty charming. Why weren't the girls there to accompany him?
