Colbert, who previously appeared in the New York Philharmonic staging of Company and also welcomed Tony and Pulitzer Prize-winning composer-lyricist Stephen Sondheim to his program, has admitted he is a fan of Broadway musicals.
His affection is on display in the clip below, where he joins McDonald for a very funny duet of "Summertime."
McDonald ( Ragtime, Marie Christine, Master Class) co-stars with Norm Lewis ( Sondheim on Sondheim, Side Show, Les Miserables) in the production that opened to critical praise Jan. 12 at the Richard Rodgers Theatre under the direction of Tony nominee Diane Paulus ( Hair, Prometheus Bound).
