I thought that a thread like this could turn out to be interesting.
I will start with a young Danish lad who just won the Danish version of X Factor.
Chresten is a very talented singer who presented himself by being totally unimpressed by the whole situation and was performing like he had done nothing else in his entire life.
I have chosen his coverversion of Lead Belly's Where Did You Sleep Last Night?, probably best known from the Nirvana version.
Chresten - Where Did You Sleep Last Night? - Lead Belly - Where Did You Sleep Last Night? (1944)
