Smith, who stars as Dusty Springfield, and Sajous, who plays Dusty's lover Claire, recorded "Baby, It's Cold Outside" on stage at New World Stages, where the musical opened Nov. 18. The video recreates a duet that Dusty Springfield performed with Rob McCuen in 1978.
Forever Dusty, according to the producers, tells the "compelling and moving story of Dusty’s journey, in a dramatic, high-energy musical filled with some of the most exciting pop songs ever written," including "Son of a Preacher Man," "You Don't Have to Say You Love Me," "The Look of Love" and many others.
