The Sir Douglas Quintet — five kids from San Antonio with an upscale moniker — scored massive hits with "She's About A Mover" and "The Rains Came" in 1965-66 by injecting the pumping Tex-Mex sound into the British Invasion. The Best Of The Sir Douglas Quintet — the ultra-rare original album, with two bonus tracks — features the soulful vocals of Doug Sahm and the signature keyboards of Augie Meyers. The Sir Douglas Quintet Is Back!, a 14-track sister compilation — stuffed with singles, B-sides and vintage unissued '65-'66 material, is the Sir Douglas Quintet album that never was. Both albums are a double-barreled loving tribute to the scintillating vocal style and songwriting talent of the late Doug Sahm.
