Sir Douglas Quintet was a rock band active in the late 1960s and early 1970s. Despite their British sounding name, they came out of San Antonio, Texas and are perhaps best known for their 1965 hit single written by Doug Sahm, the 12-bar blues "She's About a Mover" named the number one 'Texas' song by Texas Monthly. With a Vox Continental organ riff provided byAugie Meyers and soulful vocals from lead singer and guitarist Doug Sahm, the track features a Tex-Mex sound. Other influences came in from blues, jazz, and contemporary rock.
In addition to "She's About a Mover," (1965) the band is known for its songs "Mendocino," (1968) "Can You Dig My Vibrations?" (1968) and "Dynamite Woman" (1969). "Mendocino" was released in December 1968, and reached #27 in the U.S. Billboard Hot 100 by early 1969, spending 15 weeks in the chart. It was more successful in Europe selling over three million copies there.
The Sir Douglas Quintet is considered a pioneering influence in the history of rock and roll for incorporating Tex-Mex and Cajun styles into rock music. However, early influences on the band's emerging Texas style were even broader than this, and included ethnic and pop music from the 1950s and 1960s, such as doo-wop, electric blues, soul music, and British Invasion. The Quintet brought the older styles into a contemporary context, for instance by adapting the doo-wop feel, beat, and chord progressions. Perhaps even more off-beat for a late 1960s rock band than some inclusion of doo-wop type songs was that the band also played in styles like Western swing and polka (a Country & Western form and rhythmic style, from theTexas Hill Country, rather than a straight European style). They approached these styles with an instrumental line-up that was typical of blues bands: one guitarist, keyboardist, bassist, and drummer, and a member who could play either trumpet or saxophone.
