It might have been “Jesus Rock”, but it didnt have an especially “religious” sound to it. It was almost Led-Zeppelin sounding. Maybe whoever the band was just took a couple of those lyrics from the sermon?
possibly, but some of the “Jesus Rock” I have found are pretty good copies of Led Zep, sabbath, BTO, Steppenwolf. I was surprised to find out it wasn’t all “breathy” quiet stuff (although there is one who is a dead ringer for Joni Mitchell, and another that sounds like the “Mamma’s and Pappa’s). lol.
And yeah, it is a real possibility that some other band just took some of the lyrics.
