Just to clarify: Madonna has not recorded new tracks for the Andrew Lloyd Weber 70th Celebration album but a lot of tracks from the Evita soundtrack are included. However... LANA DEL REY has recorded her own rendition of "You Must Love Me" Shooketh!
As for Lana doing YML... I think the somber and melancholic nature of the song fits well with Lana's genre. Haunting, morose, melancholic and grand! I can just hear her with "Where do we go from here?" It will be great!
