Gibson and Christ got the basic idea for the musical while on drink/drug binge in Tijuana, Mexico. While intoxicated on codeine, marijuana, cheap tequila, and crack cocaine, Contrary to popular belief, crack wasn't invented by the CIA in the 1980s to keep black people down. Gibson first synthasized it in 1967, then distributed it himself for the same purposes Gibson blurted that he wanted to make a musical about the life of the Christ. Gibson forgot his idea in the morning, as he passed out in a Tijuana jail, but Christ remembered. Gibson, at first, was opposed to his own idea, but upon learning of his approxomatley $20,000 debt to Mexican drug kingpins he quickly signed on to the project.
Gibson wrote all of the music for the play in less than three weeks. It took Christ more than two months to write lyrics, which began to frustrate Mel. When Gibson saw the plot, he thought of it as an overy pompous representation of hubris, and told Jesus that if He didn't change it, he would leave the project. He loved Christ, but not that much.
Gibson fufilled his promise, quitting the project. In a fit of rage, he drafted his hit movie The Passion of the Christ as an attack against his ex-partner. As opposed to the flattering play he and Jesus co-wrote, The Passion pretty much showed Christ getting His ass kicked up and down the block for two straight hours.
Jesus Christ Superstar was a huge critical success, but the general public was unable to appreciate the work. The failure of the play started a chain of events, Jesus spent the rest of his life in bitter desperation, struggling with substance abuse, an addiction to pornography, and backstabbing Jews trying to nail him to a 2x4.
It was really John Lennon's boisterous comments that did him in though, when the Romans came to get him, his heart just wasn't in it.
