The Festival will present a starry concert July 31, 2010, to celebrate Sondheim's 80th birthday.

Directed by Lonny Price, the Gala Benefit Evening will boast the talents of Tony Award winners Patti LuPone, Audra McDonald, George Hearn and Michael Cerveris, who have all been featured in Ravinia's Sondheim celebrations since they began in 2001.

The concert will feature songs from such Sondheim musicals as Sweeney Todd, A Little Night Music, Passion, Sunday in the Park with George, Anyone Can Whistle, West Side Story and Gypsy.

Paul Gemignani will conduct the Chicago Symphony Orchestra.

In a statement Ravinia president and CEO Welz Kauffman said, "The genius of Sondheim can’t be questioned. The star power of Patti LuPone, Audra McDonald, George Hearn and Michael Cerveris make them all without peer. The stage mastery of Lonny Price and Paul Gemignani is unimpeachable. Add all this magic to the natural beauty of Ravinia Festival, and you’ve got a Gala event for the ages. In a season brimming with special anniversaries, what better way to celebrate Sondheim’s 80th birthday than by recreating the greatest hits Ravinia has had with his music and these stars over the past decade?"

The black-tie event will begin with cocktails and hors d'oeuvres on the Ravinia lawn at 5 PM; guests will then be escorted to the 7 PM intermissionless performance. Following the concert, dinner will be served in the Gala Marquee on the north lawn.
