VATICAN CITY (AP) _ Say goodbye to Lucille.

Blues artist B.B. King, scheduled to be among the performers at the Vatican's Christmas concert Friday, said he will donate his famous guitar ``Lucille'' to Pope John Paul II after the performance.

Other performers on Friday's program at Paul VI Auditorium, where the pontiff holds his public audiences, are Chaka Khan, the Portuguese group Madredeus and France's Mireille Mathieu.

The concert will raise money for the construction of 50 new churches on the outskirts of Rome.
