In 1967, the Bobby Hebb song "Sunny" was on the radio all the time. ("Sunny, thank you for the smile upon your face....") My twin sister and I were 8, and she was convinced that the song was about Jesus Christ (Sonny, not Sunny). She insisted that "Sonny One so true, I love you" was a prayer and asked the nuns if she could sing it in church.
