I have watched Andrew Lloyd Webber's Jesus Christ Superstar as well as Tommy. All of those were first introduced to me by my dad when I was a child. I have a strange love-hate relationship with Superstar. I know it's blasphemous roots and theologically am appalled by it, but at the same time, without getting verbose, my dad watched that movie and would cry every time the crucifixion scene took place. He was not a professing Christian, but I hold hope from his reaction to that scene and knowing he watched the movie and was familiar at least in small part with the gospel that there was something in his heart that was evidence of a relationship with Christ.
Tommy, on the other hand, from memory, was nothing but profane. And I had never heard that it was supposedly intended to be a parallel, symbolically or any other way, to the life of Christ. But hearkening back to those early 70s and the Jesus People movement, coupled with people who were in artistic communities and Hollywood capitalizing on anything that will make them a buck or be irreverent, nothing would surprise me.
