Willie Nelson and actor Woody Harrelson will host Willie & Woody's All Star Texas Hold 'Em Charity Tournament Sept. 27 at the Hustler Casino in Los Angeles. Nelson, Harrelson and celebrity friends will join 200 registrants and guests in a no-limit tournament that also include dinner and a silent auction. Proceeds from the event will benefit the Sustainable Biodiesel Alliance, a nonprofit organization which works to educate the public about community-based biodiesel efforts. A longtime supporter of the cause, Nelson runs his tour bus on biodiesel and is affiliated with a biodiesel brand called BioWillie.
