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 by Augie 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.
This song still gives me the shivers, after all these years.
