"The message was clear: we had to stop the crazy host," an unnamed colleague told Kurier newspaper.
Kohlhofer eventually stopped played Last Christmas when his 4-year-old daughter was put on the line and asked him to stop. "I wanted to play it all day, but because I love my daughter so much I gave in to her request," he said. Even then, he played the song one final time after seeing he'd "only" managed 23 renditions.
The station claimed the stunt, which went on for almost two hours, was not planned in advance and later posted a photo of Kohlhofer with his mouth taped shut on Facebook.
It is unlikely he will face any disciplinary action for the stunt.
Bizarrely, this is not the first such stunt in the German-speaking world to involve Last Christmas. Three years ago a DJ in Germany played the song 14 times in a row before his radio station solved the problem by taking him off air.Telegraph Group Ltd
