Stanley and Sam

I heard that story of Sam Rivers decking Stanley Crouch was true, not from Sam but from an associate of his in Orlando. They must've made up eventually -- Stanley was having a grand old time hanging out at one of Sam's 75th birthday shows at Sweet Basil's a few years ago. He was a lot more amusing than his writing. Has anyone else heard the story of Stanley, back in the day, announcing that as a writer, he could make a star out of anyone, and selecting the young David Murray for this display of potency? Parry
