Henry John Deutschendorf Jr. (December 31, 1943 – October 12, 1997), known professionally as John Denver, was an American country and folk singer, songwriter, and actor. He was one of the most popular acoustic artists of the 1970s and one of the best-selling artists overall in that decade. AllMusic has called Denver "among the most beloved entertainers of his era". Denver recorded and released approximately 300 songs, about 200 of which he wrote himself. Denver released 33 albums and singles that were certified gold and platinum in the U.S., with estimated sales of more than 33 million copies. He recorded and performed primarily with an acoustic guitar and sang about his joy in nature, disdain for city life, enthusiasm for music, and relationships. Denver's music appeared on a variety of charts, including country music, the Billboard Hot 100, and adult contemporary, earning 12 gold and four platinum albums with his signature songs "Take Me Home, Country Roads"; "Poems, Prayers & Promises"; "Annie's Song"; "Rocky Mountain High"; "Calypso"; "Thank God I'm a Country Boy"; and "Sunshine on My Shoulders". Denver appeared in several films and television specials during the 1970s and 1980s. He hosted the pilot episode of the late-night TV series, "The Midnight Special", which aired on August 19, 1972. Denver starred in the 1977 hit Oh, God! alongside George Burns. He continued to record into the 1990s, also focusing on environmental issues as well as lending vocal support to space exploration and testifying in front of Congress to protest censorship in music. Known for his love of Colorado, Denver lived in Aspen for much of his life. In 1974, Denver was named poet laureate of the state. The Colorado state legislature also adopted "Rocky Mountain High" as one of its two state songs in 2007, and West Virginia did the same for "Take Me Home, Country Roads" in 2014. An avid pilot, Denver died at age 53 in 1997, in a single-fatality crash while piloting a recently purchased light plane.
