An astronaut named Tracy Caldwell Dyson likes to sing the GARTH BROOKS song "The River" on the launch pad before heading off to space.
So on Monday Garth invited her to join him for an episode of his Facebook series, "Inside Studio G". First he showed a clip of her on the launch pad singing "The River" . . . and then he pulled out his guitar and they sang it together.
Here's the link. The launch pad clip of her singing is at 6:27. They do the duet at 7:23.
