1981 single by Lionel Richie and Diana Ross
"Endless Love" is a song written by Lionel Richie and originally recorded as a duet between Richie and singer/actress Diana Ross. In this ballad, the singers declare their "endless love" for one another. It was covered by Luther Vandross with R&B-pop singer Mariah Carey, and also by country music singer Shania Twain. Richie's friend (and sometimes co-worker) Kenny Rogers also recorded the song. Billboard has named the original version as the greatest song duet of all time.[2]
