LOS ANGELES (AP) – If you have tickets to the “American Idol” tour this summer, double check them, because the concert may be rescheduled or gone altogether. A new slate of dates has been announced, with the tour beginning on July 19 in Kent, Washington, instead of June 29 in St. Louis. The St. Louis stop has been canceled, as have the stops in Kansas City; Minneapolis; Detroit; Tulsa; Denver; Las Vegas; Ontario, California; and Oakland. The Chicago date has moved from July 6 to August 12. A tour spokesman says the change is because of “production scheduling changes.”
