"Mason Williams" (b. August 24, 1938 in Abilene, Texas) is an American guitarist and composer, best known for his popular guitar instrumental "Classical Gas". Williams wrote for the Smothers Brothers show and is also an eclectic poet and lyricist.
Mason Williams emerged in the late 1960s as a strong force in television and music circles. In 1968 he won two Grammy awards for his unique composition for guitar, "Classical Gas". That same year he also won an Emmy award for his work as a comedy writer on ''The Smothers Brothers Comedy Hour''.
Mason is perhaps most widely known as a composer and recording artist. He has recorded more than a dozen albums, five on the Warner Bros. label (''The Mason Williams Phonograph Record'', ''The Mason Williams Ear Show'', ''Music'', ''Handmade'', and ''Sharepickers''). "Classical Gas" was released as a single from ''The Mason Williams Phonograph Record'' in 1968. "Classical Gas" won three Grammys that year for "Best Instrumental (theme) Composition", "Best Instrumental (theme) Performance", and "Best Instrumental Orchestra Arrangement" (Mike Post, arranger).
