"Can't Help Falling in Love" is a song recorded by American singer and actor Elvis Presley for his fourth soundtrack album, Blue Hawaii (1961). It was written by Hugo Peretti, Luigi Creatore, and George David Weiss and published by Gladys Music, Inc. The melody is based on "Plaisir d'amour", a popular French love song composed in 1784 by Jean-Paul-Égide Martini. The song was initially written from the perspective of a woman as "Can't Help Falling in Love with Him", which explains the first and third line ending on "in" and "sin" rather than words rhyming with "you".
