The event, called "Chance and Chemistry: A Centennial Celebration of Frank Loesser", featured a star-studded cast of performers singing songs by the celebrated Broadway Composer behind Guys and Dolls, including a spirited rendition of "Adelaide's Lament" by Ana Gasteyer. Loesser's "How To Succeed In Business Without Really Trying" is set to be performed in December, with a cast led by Daniel Radcliffe.
