Associated Press, 1998-09-18 McCartney Organizing Concerts .c The Associated Press NEW YORK (AP) -- Paul McCartney will take to the concert stage next year to keep alive his late wife Linda's crusade for animal rights. McCartney and Chrissie Hynde of the Pretenders are organizing a series of concerts next year. No dates or sites have been set for what would be McCartney's first return to the stage since becoming a widower. ``Good animal activists around the world might think, `Oh, God, we've lost a very powerful voice when we lost Linda,''' McCartney said. ``Well, we have. But my voice is there now and I'm going to try to use it. We are going to keep up her good work.'' The former Beatle said he is talking with Elvis Costello, the B-52s, the artist formerly known as Prince, Blur, Lenny Kravitz and Natalie Imbruglia about participating. Mrs. McCartney died of cancer in April.
