The song "Hymne A L'Amour" (Hymn to Love) was written by French musician and singer Edith Piaf as a tribute to her lover, boxer Marcel Cerdan, who died in a plane crash in 1949. The lyrics describe the depth of love and devotion the singer has for her partner, even in the face of potential disaster or loss. She says that even if the sky falls or the earth crumbles, it doesn't matter as long as she is loved. The singer also expresses a willingness to do anything for her lover, even if it means renouncing her country, friends, or reputation. In the end, she says that if her lover is taken from her, she'll follow him into eternity. Josh Groban's version of the song is a tribute to Piaf and her legacy of love and passion. His deep, emotive voice captures the intensity and devotion of the original lyrics, and the arrangement is both delicate and powerful.
