It’s one of the most beloved duets in country music history — but “Islands in the Stream” wasn’t originally meant for Dolly Parton and Kenny Rogers at all. Written by the Bee Gees, the song was first intended for soul legend Marvin Gaye. Imagine that smooth Motown groove instead of the sweet Southern harmony we all know. But fate had other plans. When Dolly and Kenny joined forces in 1983, their chemistry turned it into a timeless crossover hit. And the rest, as they say, is music history.
