Oh my goodness, I have to share this. It's amazing. I have no idea what's happening as I've never watched this movie before but I already love it - just look at the costumes, the hairstyles, the intensity, the...uniqueness of whatever's happening there.
Actually, it may not be that unique as he's singing to her not to leave him (a common enough human action, though not always in lyrical form). Then some other girl comes and smiles and then cries and crumbles into despair.
It is now my mission to find out what happened here and if it makes any sense. I just might have to watch the entire film, diligent as I am ;-)
