A statement from the D.C. venue says that scheduling conflicts have forced the cancellation of the June 22-23 concerts. "The performances," states a release, "will not be rescheduled and the Kennedy Center will refund any purchased tickets." The concert was scheduled to reunite Tony Award winners Brian Stokes Mitchell and Christine Baranski, who played Sweeney Todd and Mrs. Lovett during the Sweeney Todd production mounted during the Kennedy Center Sondheim Festival.

Stephen Sondheim and Hugh Wheeler's Sweeney Todd originally opened on Broadway in 1979 starring Len Cariou (as Sweeney) and Angela Lansbury (as Mrs. Lovett) — both earned Tony Awards for their performances. Harold Prince directed the production, which took home the 1979 Tony for Best Musical. Subsequent revivals have starred Beth Fowler and Bob Gunton (1989 on Broadway), George Hearn and Patti LuPone (2001 concert), Brian Stokes Mitchell and Christine Baranski (2002 - Kennedy Center) and the recent Broadway revival with Michael Cerveris and LuPone.

The score includes such tunes as "The Worst Pies in London," "Johanna," "Pretty Women," "A Little Priest," "By the Sea" and "Not While I'm Around.
