When a Tony-winning diva like Patti LuPone is a gala's guest of honor, like she was at the Drama League's 27th Annual All-Star Benefit Gala on February 7, you know it’s going to be a breathtaking evening. The star was serenaded by the likes of her Women on the Verge co-stars Justin Guarini and Laura Benanti as well as Memphis star Chad Kimball, Priscilla Queen of the Desert's Will Swenson and Billy Elliot's Emily Skinner. (See Broadway.com photos here.) Now there is another reason to be happy: video of the show-stopping finale. Four-time Tony winner Audra McDonald joined LuPone on stage for a powerhouse take on the classic Barbra Streisand/Judy Garland duet “Get Happy/Happy Days are Here Again.” Click on to hear these two vocal giants join forces for an unforgettable performance.
