Written by Billy Burnette and Mentor Williams.. . Whatcha gonna do when the sun. goes down. Hop in my back seat way out of town. I know a place we can't be found. Whatcha gonna do when the sun. goes down. I've been savin' my favorite shirt. Savin' it up for a Friday night. This time I'm gonna make it work. Gonna make it work with all my might. So whatcha gonna do when the sun. goes down. Hop in my back seat way out of town. I know a place we can't be found. Whatcha gonna do when the sun. goes down. Waxin' up my shiny car. Getting' ready for the weekend. Top down we can see the stars. Blowin' that summer wind. Whatcha gonna do when the sun. goes down. Hop in my back seat way out of town. I know a place we can't be found. Whatcha gonna do when the sun. goes down. Let's hide away and let the feelin' in. I wanna hear you say you love me. once again. Let's hide away and let the night begin. Oh-watcha gonna do when the sun. goes down. Hop in my back seat way out of town. I know a place we can't be found. Whatcha gonna do when the sun. goes down. .
