James Brennan will direct the semi-staged concert performances of My Fair Lady, which will play Avery Fisher Hall March 7-10. Rob Fisher will conduct the famed orchestra. The creative team also includes Ken Billington (lighting design), Ray Klausen (set design), Gail Baldoni (costume design) and Peggy Hickey (choreography).

My Fair Lady replaces the originally announced staging of Company. Plans to mount that Stephen Sondheim-George Furth musical were canceled in May due to the Broadway revival of the musical currently onstage at the Ethel Barrymore Theatre.

My Fair Lady is based on George Bernard Shaw's Pygmalion and features a book and lyrics by Alan Jay Lerner and music by Frederick Loewe. The original Broadway production opened on March 15, 1956, ran for over six years and won nine Tony Awards, including one for Best Musical. The score contains such Broadway classics as "I Could Have Danced All Night," "On the Street Where You Live," "Wouldn't It Be Loverly?" and "Get Me to the Church on Time."

Show times are March 7 and 8 at 7:30 PM and March 9 and 10 at 8 PM. Tickets, priced $65-$245, may be purchased by calling (212) 875-5656 or by visiting www.nyphil.org.
