Four-time Grammy winner Olivia Newton-John knows a thing or two about music, so on October 28, when she and her husband, John Easterling, decided to have a Broadway date night, the couple picked the soulful new tuner A Night with Janis Joplin. Written and directed by Randy Johnson, the musical features the iconic songs of Janis Joplin and stars powerhouse Mary Bridget Davies as the legendary rock singer. After the high-energy performance, Newton-John and Easterling headed backstage at the Lyceum Theatre to meet Davies and the talented cast.
