Jonas Ekfeldt

Jonas Ekfeldt born (June 29, 1971) is a Swedish music producer and singer. In 1996, using the name Robin Cook, he released the single "I Won't Let the Sun Go Down" (a cover of Nik Kershaw's debut "I Won't Let the Sun Go Down on Me") followed by "Comanchero" and the album "Land of Sunshine" in 1997.
Ekfeldt sang and produced "I Won't Let the Sun Go Down" and all subsequent releases under the name Robin Cook, but appointed Manuel Manci to front and perform, thinking he himself lacked time. The truth of who really was the singer was kept secret until Swedish newspaper "Aftonbladet" ran an article in 2002. Yet another single was released in 2002 under the name Robin Cook, titled "Susanna" with Ekfeldt on the cover.
Sampled by Sveriges Radio.
Ekfeldt filed a lawsuit against, and won over, Sveriges Radio for sampling "I Won't Let the Sun Go Down".
