I just got off the phone with a spokesman for Major League Baseball, and he clarified that Elvis Costello is
not opening for
Sheryl Crow next Saturday, July 11, nor is he doing an entirely separate set of his own material. He'll come out during the show and join her for some songs. In other words, he'll be a special guest. The show, which takes place under the Arch, is still starting at 8 p.m.
