If/Then star Idina Menzel and composer Tom Kitt stopped by WNYC’s Soundcheck to chat and perform snippets from the new musical. In the interview, the Tony-winning superstar discussed the “huge responsibility” of her first above-the-title performance on Broadway, motherhood, the “smart and with-it” Fanzels and balancing the dual roles she takes on in If/Then. “I offered to sing Beth as an operatic singer and Liz as a jazz singer,” Menzel joked, “but we thought that was too on the nose.” Oh, and what’s up with that Christmas album?! “I’m enjoying making it!” she said. “These are the most beautiful songs; the melodies are incredible.” Who cares if she’s Jewish? As Kitt says, “All the good Jews do Christmas albums.” Take a look at their live performance of “You Learn to Live Without” below, and see Menzel in person at the Richard Rodgers Theatre!
