- 'O Sole Mio - What a beautiful thing is a sunny day! The air is serene after a storm, The air is so fresh that it already feels like a celebration. What a beautiful thing is a sunny day! But another sun, that's brighter still, It's my own sun that's upon your face! The sun, my own sun, It's upon your face! It's upon your face! When night comes and the sun has gone down, I almost start feeling melancholy; I'd stay below your window When night comes and the sun has gone down. But another sun, that's brighter still, It's my own sun that's upon your face! The sun, my own sun, It's upon your face! It's upon your face!
