Canned Heat is a blues-rock band that formed in Los Angeles, California, USA, in 1965. The group has been noted for its own interpretations of blues material as well as for efforts to promote the interest in this type of music and its original artists. It was launched by two blues enthusiasts, Alan Wilson and Bob Hite, who took the name from Tommy Johnson's 1928 "Canned Heat Blues", a song about an alcoholic who had desperately turned to drinking Sterno, generically called "canned heat". (Sterno Canned Heat is a fuel made from denatured and jellied alcohol.Sterno has long been mixed with water and other liquids to produce a drink called "canned heat", "squeeze" or "pink lady"). Arriving via helicopter at Woodstock, Canned Heat played their most famous set on the second day of the festival at sunset. The set included "Going Up the Country" which became the title track in the documentary, even though the band's performance was not shown. The song was included in the first (triple) Woodstock album; while the second album, Woodstock 2, contained "Woodstock Boogie".
"Sometimes I Feel Like a Motherless Child" (or simply "Motherless Child") is a traditional Negro spiritual. The song dates back to the era of slavery in the United States when it was common practice to sell children of slaves away from their parents.Like many traditional songs, it has many variations and has been recorded widely.
