The Bee Gees wrote "Islands in the Stream" with Marvin Gaye in mind, but they took a left turn and turned it into one of the most successful country ballads of all time thanks to Kenny Rogers and Dolly Parton. The duet "Islands in the Stream" topped the Country, Adult Contemporary, and Hot 100 in 1983.

Kenny Rogers & Sheena Easton "We've Got Tonight"

Five years after Bob Seger released the ballad "We've Got Tonight", Kenny Rogers put his signature touch on it.  Unlike Seger, Rogers turned the song into a duet and enlisted the help of Sheena Easton.  Kenny's magic paid off as the song went to #2 on the Adult Contemporary Chart and #1 on the Country Chart.
