The social highlight of the year comes around again. Beer will be consumed, laughs will be had and there will be jeering at the fixed voting.... We can be fairly sure that NONE of the following will be contestants:
Arch Enemy - Sweden
Sparks-= USA but could represent anyone
Laibach - Slovenia
However some famous singers did do a Eurovision entry early in their careers and went on to better things, particularly Ofra Haza (and Celine Dion too, sadly).
