I'm not sure if there's been any such cases in Eurovision history - certainly not very recently, but what really happens if an artist is entirely incapable of performing - either unable to sing, sent to hospital or absent for other reasons. Hell, they could just even decide to "screw it" at the last moment and refuse to show up - which almost happened with Sweden 2009.
If it's one person who's part of a group i guess it would be acceptable to find a substitute, but what it if it's a solo artist? Can the national team just find someone else to sing the same song at last moment's notice? Would that be allowed, if the original artist is unable to perform?
