LONDON (AP) ? Grammy award winner Adele canceled two sold-out weekend shows at London's Wembley Stadium, telling fans early Saturday that her vocal cords were damaged and that she was advised by a doctor not to perform. In a statement to her fans on social media, Adele said she considered going ahead with her Saturday night performance but didn't think she would have been able to make it through the show and didn't want to "crumble" on stage.
