Rose Royce was a group that had tried to make it for several years but they just couldn't pull it together. They were about to hang it up when they were asked to do the music for a movie in 1977, so they went for it. They changed their name to Rose Royce and recorded the title song for the film. Thus a huge hit was born, and so was a group that had many hits after this song. Here's Rose Royce with Car Wash! Get ready to clap!!
