William "Willie" Hugh Nelson is an American country singer-songwriter, author, poet and actor. He reached his greatest fame during the outlaw country movement of the 1970s, but remains iconic, especially in American popular culture. In recent years he has continued to tour, record, and perform, and this, combined with activities in advocacy of marijuana, as well as a well-publicized 2006 arrest for marijuana possession, have made him the subject of renewed media attention.
