When he was 16, James Burton was inventing the American guitar. He'd been born in Dubberly, La., in 1939, and was apparently self-taught on his instrument. At 15, he cut a single backing local singer Carol Williams, and then one day he came up with a guitar riff that he liked. He took it to a singer from Shreveport he was touring with, and they worked out a song to use in his act. One thing led to another, and it wound up on a record called "Suzie Q," credited to Dale Hawkins, the singer.
