Remember Dana International? You probably do if you're a fan of the Eurovision Song Contest, since she was the one who last won it for Israel in 1998, with the dance tune Diva – although it was her past life as a man which grabbed more headlines than her victory, and made her one of the more controversial winners of recent years. Born Yaron Cohen in Tel Aviv in 1972, she began her career as a female impersonator, before having a sex change and becoming Sharon Cohen when she was 21. She had already established herself as a chart star before Eurovision came along, thanks to a string of hit albums in Israel and the Middle East. Now she is back with a new song. If the chorus sounds familiar, it's because it's taken from a 30-year-old children's song.
