Originally this pop song was sung by Celine Dion, but in film it has been performed by Richard Harris, together with J. Levy, J. Hough & Zac Efron. This is not the only existing cover – it also had been sung by Johnny Mathis, Glee Cast, Clay Aiken, Stefania, John Tesh, Gregorians and many-many others. It gave a start to a whole heap of variants, because it is a gentle and full of love. One of the best on love quantity. Celine Dion has dedicated it to her husband (who passed away in 2016).
