David Cook took to his Web site to update his fans with some news about his live show. The former American Idol champ wrote that his bassist Joey has actually left the band and they are currently looking for a replacement. It won’t affect Cook’s scheduled dates though, and he even announced that he’ll be performing in New York City as part of Good Morning America’s Summer Concert Series on August 7th.
