"Lullabye (Goodnight, My Angel)" is the seventh track and third single from Billy Joel's 1993 album River of Dreams. Joel wrote this as a lullaby for his 7-year-old daughter Alexa Ray in response to her question, “Where do we go when we die?" In 2004, it was announced that Joel had agreed to write two children's books for Scholastic, the U.S. publisher. The first book was entitled Goodnight, My Angel (A Lullaby) and is a picture book based on the song. “Reassuring children that they are not alone or could be abandoned is very important for their well-being,” Joel said in a statement in 2004.
