This lineup for the August 23 Hartford, Connecticut, stop on the Oddball Comedy and Curiosity Festival tour was already amazing (what the New York Times afterward called “a murderer’s row of comics”). Then, after listed closer Louis C.K. finished, there appeared an astonishing bonus: Dave Chappelle– not part of the Oddball tour this year– came on to do the night’s closing set. Last year, Chappelle, a headliner on the 2013 Oddball tour, clashed with the audience and walked off, later vowing never to return to Hartford. So you could say Sarah was part of a historic night of comedy in Hartford yesterday.
