Patti Smith released her 11th album, Banga, last week, which we’re proud to say we liked. To celebrate the new LP, she stopped by the Late Show to play the title track for David Letterman. The performance is great and belies the punk icon’s 65 years, but we couldn’t help but notice at the beginning of the video that freakin’ Bootsy Collins is sitting in on bass with Paul Schaffer in Letterman’s house band. What a missed jam opportunity! Patti does blow Bootsy a kiss at the end, though.
