Superstar is the story of a band groupie who holds a strong love for a musician. After a short affair, he has moved on to the next town. She is alone, waiting and yearning for a return that will never come. Despite his promises to see her again, the music on the radio is all she has left. 

The song was written in 1969 by Delaney and Bonnie Bramlett who released it as a B-side. Versions by Cher and Bette Midler in the early 1970’s were never really successful. The most famous version is by The Carpenters, probably because of the way Karen Carpenter depicts the deep longing and loneliness in her voice.
