Johnny Mathis & Deniece Williams - Too Much, Too Little, Too Late (1978)

"Too Much, Too Little, Too Late" is a song performed by singers Johnny Mathis and Deniece Williams. Lyrics and music are arranged by Nat Kipner and John Vallins. Released as a single in 1978, it reached number 1 on the U.S. Billboard Hot 100 pop chart, Adult Contemporary chart, and R&B chart. Outside the U.S., the song peaked at number nine on the Canadian Singles Chart and number three on the UK Singles Chart. "Too Much, Too Little, Too Late" was certified gold and silver in the US and in the UK by the RIAA and the British Phonographic Industry respectively. The single was a comeback of sorts for Mathis, as it was his first chart-topping hit in the US since 1957's "Chances Are".

Later in 1978 the duo released a follow-up single, "You're All I Need to Get By" (which peaked at number 47 on the Hot 100), and a full album of duets, That's What Friends Are For. The success of the duets with Williams prompted Mathis to record duets with a variety of partners including Jane Olivor, Dionne Warwick, Natalie Cole, Gladys Knight, and Nana Mouskouri. A compilation album, also called Too Much, Too Little, Too Late and released by Sony Music in 1995, featured the title track among other songs by the Mathis/Williams duo.
