In July 1969, just prior to Woodstock, "Hallelujah", their fourth album was released. The "Melody Maker" wrote: "While less ambitious than some of their work, this is nonetheless an excellent blues-based album and they remain the most convincing of the white electric blues groups." The album contained mainly original compositions with lyrics relating to the band such as Wilson's "Time Was" and a few re-worked covers like "Sic 'em Pigs" (Bukka White's "Sic 'em Dogs") and the original "Canned Heat" by Tommy Johnson.
