Douglas Wayne Sahm (November 6, 1941 – November 18, 1999) was an American musician, singer-songwriter and multi-instrumentalist born in San Antonio, Texas. Sahm is regarded as one of the main figures of Tex-Mex music, and as an important performer of Texan Music. He gained fame along with his band, the Sir Douglas Quintet, with a top-twenty hit in the United States and the United Kingdom with "She's About a Mover" (1965). Sahm was influenced by the San Antonio music scene that included conjunto and blues, and later by the hippie scene of San Francisco. With his blend of music, he found success performing in Austin, Texas, as the hippie counterculture soared in the 1970s.
