Willie Nelson (born April 29, 1933, in Abbott, Texas) is a 1933-04-29 year-old country musician, revered for his distinctive voice, commitment to social causes, and impact on the outlaw country music genre. During the 1960s and early '70s, he had a string of top 100 hits on the US Country chart, with his first number one, "Blue Eyes Crying in the Rain," dropping in 1975. He's since released over two dozen number-one hit singles including "Blue Skies," Always on My Mind," and "On the Road Again." Nelson is also a well-known social activist, serving as co-chair on the advisory board for the National Organization for the Reform of Marijuana Laws, co-founding Farm Aid in 1985, and starting his own brand of biodiesel fuel. His contributions are well-recognized, with inductions into the Country Music Hall of Fame in 1993, the National Agricultural Hall of Fame in 2011, the Texas Institute of Letters in 2018, and the Rock and Roll Hall of Fame in 2023, among many other honors.
