American Idol champ David Cook canceled two shows at college campuses in New Hampshire and Connecticut on Monday and Tuesday due to “family matters,” reports, citing an announcement the singer made on his website. Cook’s brother has been battling brain cancer for more than a decade. Cook is still expected to appear on Wednesday’s American Idol in a taped performance, and he plans to return to touring on Thursday.
