Williams cancels appearance at IU Auditorium

MIAMI – Robin Williams needs heart surgery and must cancel the remainder of his one-man comedy show, "Weapons of Self-Destruction," his publicist said Thursday.

Williams was scheduled to appear at IU on March 26.

The 57-year-old actor needs an aortic valve replacement, Diane Rosen said in a news release. Williams' representatives would not say when the comedian was admitted to the hospital or where he was.

"I'm so touched by everyone's support and well wishes," Williams said in the statement. "This tour has been amazing fun, and I can't wait to get back out on the road after a little tune-up."

Williams was already in Florida when he canceled four shows in the state earlier this week after experiencing shortness of breath.

Since September, he had been on the sold-out, 80-city tour, which is expected to resume in the fall, his publicist said. Tickets will be honored once the new dates are scheduled, or people can contact their place of purchase for refunds.
