Willie Nelson abruptly ended his concert in San Diego last weekend after coughing and experiencing breathing difficulties during the first song of his performance.
A publicist for the 84-year-old Nelson says the country music legend is recovering from the flu and shows scheduled this week in Rohnert Park, California; Las Vegas; and Laughlin, Nevada, have been canceled.
The San Diego Union-Tribune reported that Nelson left his show at a San Diego casino on Saturday after the first song, "Whiskey River."
Fans said Nelson was coughing and apparently had difficulty breathing. A statement from Ticketmaster said he left the stage early because of an illness.
Nelson keeps up a rigorous touring and recording schedule. His latest album, "Willie Nelson and the Boys: Willie's Stash Vol. 2" featuring his sons Lukas and Micah, was released last year.
