5 10 15 Hours

"5-10-15 Hours" is a rhythm-and-blues song written by Rudy Toombs in 1952 for Ruth Brown and was one of several number-one R&B hits he wrote for her. Her recording is smooth, sophisticated blues shouting at its best, has a touch of suppliance more characteristic of the vocal qualities of popular singers than of the blues. The recording features a tenor sax solo by Willis Jackson.

When Brown was inducted into the Rock and Roll Hall of Fame, her induction said that "her best work was to be found on such red-hot mid-Fifties R&B sides as '5-10-15 Hours'".
