Richie said “unfortunately my recovery from a knee procedure will not have me 100 percent ready to start the tour.” He said he doesn’t want to disappoint his fans and he’s looking “forward to being back onstage so we can all be ‘Dancing on the Ceiling’ together again.”

Purchased tickets will be honored at the new dates, to be announced soon.
