Lupe Fiasco Performs 'The Show Goes On' on 'Letterman'

Lupe Fiasco returned to the Late Show With David Letterman last night to perform "The Show Goes On," a cut from his new album, Lasers. The song, which interpolates hooks from Modest Mouse's hit "Float On," was a good choice for the appearance – the rocked-up energy of his live band brought out an aggressive quality in the often laid-back Lupe.
