Legendary songwriter and record producer Cowboy Jack Clement joined the Broadway cast of Million Dollar Quartet at the Nederlander Theatre during the finale of the April 21 evening performance of the musical. He performed "It'll Be Me."

The show has been inspired by the famed 1956 recording session that brought together Jerry Lee Lewis, Johnny Cash, Carl Perkins, and Elvis Presley -- along with Sam Phillips, founder of Sun Records. Clement was also present at the session, serving as the engineer.
