All eyes were on Willie Mays, Hank Aaron, Yogi Berra and the rest of the 40 Hall of Famers who lined Yankee Stadium’s infield before Tuesday’s All-Star game. But Major League Baseball couldn’t resist a little extra eye candy beyond the B-2 stealth bomber fly-by. Singing the national anthem in tight white jeans, a star-spangled halter and stilettos, Sheryl Crow helped warm up the crowd. As the night wore on, Sarah Jessica Parker drew boos before her charitable pitch for cancer. Even Katie Couric appeared more welcome. Dressed in a skintight T-shirt, Bermuda shorts and heels, she made the rounds, occasionally greeting beer-drinking strangers. The Village People, who belted out “YMCA” in between innings, were more recognizable in their signature garb. But what grabbed the attention of Nicole Miller, who caught the game with Bud Konheim and his wife, Colleen, was Joan Jett who rocked out Randall’s Island at a pregame feast in pelvic bone-baring, low-waisted jeans and a bikini top. “She looked fantastic,” Miller said. Game goers may have thought the same of the designer, who wound up on the Jumbotron in the seventh inning.
