Three hot, black lady singers who wear sparkly dresses and sing backup for a band. Blackups originated in the 50's and 60's, but they are so hot and good, they can be used anywhere anytime.
Guy singer: Here I am, baby. Signed sealed delivered, I'm yours.
Blackup singers: Oooooh, baby. Yeah...you got the future in your hands. (in harmony with eachother)
