Stephen Colbert showed his love for Broadway, and his skill at musical comedy, by appearing in a concert version of Stephen Sondheim’s Company – at the composer’s request. Tonight, in character as his conservative blowhard, he plays host to one of the most talented performers in Broadway history: Audra McDonald, who’s just been nominated for a sixth Tony Award, for Best Performance by a Leading Actress in a Play, for her harrowing, haunting impersonation of Billie Holiday in Lady Day at Emerson’s Bar and Grill. I saw it, and her, and she deserves to win the Tony. And if she does, it’ll be a record sixth for a performer. She’s covered both the acting and musical categories, as both featured actress (Carousel in 1994, Master Class in 1996, Ragtime in 1998) and leading actress (A Raisin in the Sun in 2004, Porgy and Bess in 2012).
