Yes, they wrote it. The Bee Gees wrote over one thousand songs. This one they wrote for Kenny Rogers but Kenny didn’t like singing it by himself. Then somebody said, “Hey, Dolly Parton’s somewhere around the studio. Let’s get her to sing along.”
And she did. And he did. And they did. And then Everybody sang along. You know it, my friends. Sing it. Sing it out. It will enhance your day in ways you cannot know yet, so sing it and go see what’s out there. Sail away with me to another world and we rely on each other. Ah ha.
