Robin Williams is returning to the road this fall to resume his Weapons of Self-Destruction and Reconstruction comedy tour after he postponed dates in March to undergo heart surgery.
The actor, 57, who is set to make his first public appearance Wednesday on The Late Show with David Letterman, underwent more than three hours of heart surgery to replace his aortic valve, repair his mitral valve and correct his irregular heartbeat.
"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."
Williams also returns to the big screen on May 22 as Teddy Roosevelt in the sequel Night at the Museum: Battle of the Smithsonian.
