You Light Up My Life is an album by American pop singer Johnny Mathis that was released on March 13, 1978, by Columbia Records. While this LP includes three new songs ("All I Ever Need", "I Wrote a Symphony on My Guitar", and the hit pairing with Deniece Williams, "Too Much, Too Little, Too Late"), it doesn’t stray too far from the format of his albums of recent years in covering established material, including a standard ("Where or When"), a country number ("It Was Almost Like a Song"), something from Broadway ("If You Believe"), and a few soundtrack tunes (the title track, "How Deep Is Your Love", "Till Love Touches Your Life").
