Oct. 26 1957: Thousands of San Francisco adolescents were "shook up" by Elvis Presley, the hip-waving vocalist from Tennessee. Presley, wearing a pompadour, a pout, sideburns to his chin and a wine-red suit, played at the Civic Auditorium to afternoon and evening audiences whose shrieks carried down to Market Street. Whether the predominantly female audience came to hear Presley sing or to watch his caricature of sex could not be determined. They roared through every one of his 14 rock 'n' roll offerings with such volume that three police officers and four firefighters were forced to leave. Three minutes before he burst onstage, he confided to backstage reporters one chilling note. He will release an album of seasonal songs at Christmas time. The only song he hasn't monkeyed with, he said, is "Silent Night." "It'll be a rock 'n' roll Christmas," he said.
