Jerry Lee, Carl, Elvis, Johnny and Marylin Evans
"On December 4 1956, the couple, along with some of Elvis's friends, cruised around Memphis, as usual. But on this day Elvis stopped at Sun, where he had made his first record only three years prior. It was there, over the next few hours, that fate (and a tape recorder) would allow a rare glimpse of the musical passions of these four future legends, as they jammed on gospel, country and blues. It was a seminal session of rock 'n' roll's origins ... and one that Maryiln Knowles-Riehl barely recalls."
