Soul Hustler (1973)

"May the Lord have mercy on your soul..."

Matthew Crowe, a whoring, pot-smoking, wandering singer teams up with a tent-show preacher. The preacher recognizes Mathew's charisma, and together they collect big donations delivering sermons with rocking gospel songs.Soon enough, Matthew lands a record deal, and the older man becomes the manager of Crowe's new act: Matthew, Son of Jesus. They hire a backup group of mustachioed rock musicians, who play in brown monks' robes, in contrast to Matthew's white robe and sandals. Their debut album becomes a huge hit so they go on a concert tour to promote it.
