elvis plays his first show

At the Overton Park Shell (July 30), Presley, Moore, and Black were billed as The Blue Moon Boys, with Slim Whitman headlining.[43] Presley is said to have been so nervous during this show that his legs shook uncontrollably. His wide-legged pants emphasized his leg movements, apparently causing the young women in the audience to go 'crazy'.[44] Though initially uncertain about what caused the fans to scream, Presley consciously incorporated similar movements into future shows.[45] DJ and promoter Bob Neal, who had been approached by Sam Phillips to get Presley on the Overton Park bill, was now the trio's manager (taking over from Scotty Moore).
