Karaoke night meets office party in "Happy Hour," the latest concoction from Ms. Barnes and Anna Bass, best known these days as the dancers - alongside the radio personality Ira Glass - in the touring revue "Three Acts, Two Dancers, One Radio Host." Their new weekly gig, in a Lower Manhattan dance studio, features the cheeky duo playing two guys playing their everyday selves, as Ms. Barnes continues her love affair with awkwardness, failure and physical comedy. The audience gets drinks, prizes and the chance to sing.
