Among the album's participants were Deep Purple's Ian Gillian, members of Joe Cocker's Grease Band, the Hair alumnus Head, and an unknown Yvonne Elliman. The project at once fed off of and stoked the Jesus revival you could hear burgeoning in numerous early seventies radio hits, all of which jibed nicely with the era's soul-searching and its eye for long hair and beards.
A 1971 Billboard story by Elliott Tiegel on the trend ("Jesus Christ, Are You Here Again? Or, Rock Meets the Guy from Above") mentioned that Los Angeles MOR mothership KMPC played the entire album on Thanksgiving 1970 and on Easter 1971. And although the occasional story would surface that a given outlet had banned the album for being too sacrilegious, the consensus would echo Tiegel's assertion that Jesus Christ Superstar was the "granddaddy" of all the era's "Jesus stories."
