Book excerpt: An only child, a mama's boy-Elvis was a shy kid who struggled to make friends and found comfort singing in church and learning guitar. While in high school, he continued his music but was often ridiculed by students. On a whim, he recorded a song for his mom's birthday at Sun Record Studios as part of a customer promotion. The studio loved it so much that they sent it to local record stations . . . and the rest is history. Here is the story of how a poor kid from Tupelo, Mississippi, became an American legend.
