On Valentine's Day, WQXR presented "Passion in the Afternoon" — a lunchtime conversation with beloved composer Stephen Sondheim and director John Doyle, hosted by Elliott Forrest. The event featured love songs from some of Sondheim's most celebrated shows, performed by cast members of Classic Stage Company's new production of "Passion."

"We'll think of this as the first-ever in history Sondheim singing Valentine's telegram," Melissa Errico said before performing "(Not) Getting Married Today" from the Sondheim musical comedy "Company." Watch the performance below.
