Nathaniel Adams Coles (March 17, 1919 February 15, 1965), known professionally as Nat King Cole, was an American musician who first came to prominence as a leading jazz pianist. Although an accomplished pianist, he owes most of his popular musical fame to his soft baritone voice, which he used to perform in big band and jazz genres. He was the first black American to host a television variety show and has maintained worldwide popularity over 40 years past his death; he is widely considered one of the most important musical personalities in United States history. "Unforgettable" is a popular song written by Irving Gordon. The song was published in 1951.
The most popular version of the song was recorded by Nat King Cole in 1951, with an arrangement written by Nelson Riddle. A non-orchestrated version of the song recorded in 1952 is featured as a bonus track on the CD reissue of 1955's completely instrumental (save the bonus material) Penthouse Serenade. Cole again recorded the tune ten years later, in a stereo version recorded for the album The Nat King Cole Story. His version of the song was included extensively in the 2009 film Watchmen.
