The BBC reports:
The winner of the search to find Germany’s Eurovision Song Contest entrant turned down the chance to represent his country on live TV. Andreas Kummert initially thanked the public for selecting his song Heart Of Stone as Germany’s entry. But, shortly afterwards, he took the microphone from presenter Barbara Schoneberger and said: “I’m really not in the right shape to accept this.” Instead, he said, “I give my title to Ann Sophie”, the 24-year-old runner-up. Ann Sophie looked visibly confused by the turn of events; while many in the studio audience booed. After being confirmed as the winner, the singer turned to the audience and asked them “do you even want this?” Finally accepting her fate, she launched into her song, Black Smoke.
Kummert’s folksy entry is here. The first clip below is subtitled and the default winner’s entry is after that.
