"It's the highest song I've ever had to sing, notes that I really don't have. And somehow they came out of nowhere. I was frightened to do it, I haven't made a film in forever. But I was thrilled to do it because it gave me so much satisfaction." Superstar Cher feared she wouldn't be able to hit all the high notes in the song You Haven't Seen the Last of Me, which she performs in movie musical BURLESQUE.
