"I Won't Let the Sun Go Down on Me" is a song by English singer-songwriter Nik Kershaw from his debut studio album, Human Racing (1984).

(Waterman managed Collins at the time the song was recorded, but had no involvement in the actual production of the track.

In September 1984, Kershaw told Number One magazine:[4] It's probably not immediately obvious but "I Won't Let the Sun" is about The Bomb, or rather about people taking responsibility for what they do generally.

It's saying that it probably won't do much good for one person to shout about these things but I'm going to anyway.The song was originally written as a folk protest song, but as Kershaw's manager had signed him up to Peter Collins and Pete Waterman's Loose Ends production company, it turned into a pop anthem in the studio.

The original video for "I Won't Let the Sun Go Down on Me" shows Kershaw singing the song on a hillside and in a castle.

Swedish producer Jonas Ekfeldt recorded his version of the song as Robin Cook in 1996, under the title "I Won't Let the Sun Go Down", which was later included on the album Land of Sunshine (1997).

[29] Ekfeldt filed a lawsuit against Sveriges Radio for sampling "I Won't Let the Sun Go Down" and accused them for using the sample without permission in the parody "I Won't Let Susan Go Down on Me" on the album Rally 2 from the radio programme Rally on the channel SR P3.
