ST. LOUIS (AP) - He's a legendary blues guitarist. But at the age of 88, the way B.B. King is giving some fans the blues is becoming a problem for music lovers. He continues to tour - and sometimes his age and illness shows. He performed this past Friday in St. Louis - and some fans were none too pleased. Some left early after King performed just a few snippets of some songs, rambled on between others - and had difficulty playing and keeping up with his band. One fan says while he sees King as a "living legend" and admires the man and his music, he was disappointed to shell out $150 to see him and not get a full show. Some music fans say aging acts like King should get some slack from fans because of their stature - not heckled for being slowed by time.
