Guess the 1960s song lyrics #252

*First line is the artist name. 1966. Both of this artist's parents were blind musicians. This artist started performing with his older brother Harold when he was just 3. The day after John Kennedy was assassinated, Harold was stabbed to death outside a nightclub which devastated him. He wrote this song after about preferring to adopt an uplifting disposition over a lousy one. It hit #2 on the Billboard and #1 on Cash Box.
