Lullabye is the third single from Billy Joel's 1993 album River of Dreams. It was inspired by Alexa Ray Joel, his daughter by Christie Brinkley. The song was originally written as a prelude to the song "The River of Dreams" in the style of a monophonic Gregorian chant. Joel had written English words in the chant describing a man who had lost his faith, and had then had the words translated into Latin. He changed his mind upon hearing the recording, and incorporated it into the song River of Dreams. He later removed the interlude from the final studio version of "River of Dreams", and instead wrote lyrics to the melody that reflected his sentiment toward Alexa Ray, who was a young child at the time of writing.
This is a hauntingly emotional arrangement that is best listened to with your eyes closed as you float away, wrapped up in the warmth of a Fathers love as he spends the last few moments with his daughter at she goes off to sleep.
