If I could sing like anyone else, I'd want to sing like Cleo Laine. I first fell in love with her singing when I discovered the London revival album of Showboat at the library. She played Julie, and her version of Can't Help Lovin' Dat Man of Mine is still one of my all time favorite songs.
I love her versions of jazz songs, popular songs, and Broadway songs. No One is Alone is from Stephen Sondheim's musical, Into the Woods:
