Local pop artist Jeremy Messersmith is scheduled to perform Wednesday night on "The Late Show With David Letterman." We emphasized "scheduled" because of the evening's other two guests: Kathy Griffin and Ken Burns, both of whom have a tendency to talk and talk and talk -- to the point where Messersmith could get bumped.

Unlikely, though. Letterman seems to be enjoying his Minnesota music these days. Trampled By Turtles made a triumphant appearance last month.

While Messersmith's gig has nothing to do with Robin Williams, we can't help but mention how touching it was Monday to watch Letterman pay tribute to the late comic. If you haven't seen it, check it out:
