Attendees at the American Theatre Wing's annual gala at the Plaza Hotel received a rare treat: a live performance from Oscar and Grammy winner Jennifer Hudson! The September 26 event, which honored longtime American Theatre Wing board member Sir Howard Stringer, a.k.a. Chairman, CEO and President of Sony Corporation, raised more than $550,000 for the Wing's education and outreach programs. Broadway favorites like Angela Lansbury, Elaine Paige, Colin Donnell and Kelli O'Hara were also on hand to support the cause.
