This song is a classic!! It was written by Cher in 1966, and it's one of the most covered songs ever. There are a lot of versions in Asia and specially in Italy through the last five decades. This one is performed by Lady Gaga, who started singing jazz when she was 16. It seems that she's coming back to her origin. If you like it and have some time, look for the full album: Tonny Bennet & Lady Gaga. Have fun!!
