As previously reported, the June 5 concert will boast the talents of George Hearn (Arthur), Sylvia McNair (Guenevere) and Rod Gilfry (Lancelot), who were the leads in Ravinia's 2007 performance of Frank Loesser's The Most Happy Fella.

Newly announced for the cast are Steve Calzaretta, Robert Hunt, David Lively, Susan Moniz, Summer Smart, George Andrew Wolff and Max Quinlan.

Marc Robin will direct the cast with Paul Gemignani leading the Ravinia Festival Orchestra. (Gemignani recently stepped in for the previously announced Erich Kunzel, who has been diagnosed with pancreatic cancer.)

Camelot — featuring music by Frederick Loewe and book and lyrics by Alan Jay Lerner — originally opened at Broadway's Majestic Theatre in Dec. 1960, playing 873 performances before closing Jan. 5, 1963. The premiere company included Richard Burton, Julie Andrews, Robert Goulet, Robert Coote, John Cullum and Roddy McDowall. The classic Lerner and Loewe score boasts such tunes as "If Ever I Would Leave You," "I Loved You Once in Silence," "Follow Me," "I Wonder What the King Is Doing Tonight" and the title tune.

The 1960 musical, according to press notes, "focuses on the love triangle between the legendary liege, his lady Guenevere and Sir Lancelot." Tickets are available by visiting www.ravinia.org.
