In October the band released their third album, "Living the Blues", which included "Going Up the Country", their best-known song. Wilson's incarnation of Henry Thomas' "Bull-Doze Blues" was almost a note-for-note copy of the original, including Thomas' instrumental break on the "quills" (pan-pipes) which Jim Horn duplicated on flute. Wilson rewrote the lyrics with a simple message that caught the "back-to-nature" attitude of the late 1960s. The song was a hit in numerous countries around the world (#11 on the U.S. national chart) and would go on to become the unofficial theme song of the Woodstock Festival as captured in Michael Wadleigh's 1970 documentary. The album also included a 19-minute experimental track "Parthenogenesis", which was a nine-part sound collage of blues, ragas, jaw-harp sounds, guitar distortion and other electronic effects; all pulled together under the direction of manager/producer, Skip Taylor. Longer still is "Refried Boogie", clocking in at over 40 minutes, recorded live at the Kaleidoscope.
