LOS ANGELES (Reuters) - Comedian Robin Williams, recovering from heart surgery, will resume his "Weapons of Self-Destruction" stand-up tour in September, his representatives said on Wednesday.
Williams, 57, had to postpone the tour in early March after complaining of shortness of breath. He had surgery that month at the Cleveland Clinic in Ohio to replace his aortic valve, repair his mitral valve and correct an irregular heartbeat.
Williams, who got a transplanted cow heart valve in the operation, was scheduled to make his first major public appearance on Wednesday on CBS' "The Late Show with David Letterman."
"This little break has given me more energy than ever," Williams said in a statement. "Plus it's wonderful to have a cow valve ... if you don't mind the grazing, it's quite invigorating."
Replacing a faulty aortic valve with a valve from a cow is a common method of treating the heart ailment.
Williams, known for his manic stand-up routine steeped in wacky accents and improvisation, will resume his tour on September 30 in Bloomington, Indiana.
The resumed tour has 29 dates, including stops in Atlanta, Detroit and Washington. It ends November 28 in Atlantic City.
Williams won an Oscar for his supporting role as a psychologist in the 1997 drama "Good Will Hunting." He will reprise his role as the late U.S. President Theodore Roosevelt in the comedy sequel "Night at the Museum: Battle of the Smithsonian" that opens on May 22.
