Geert Chatrou is a Dutch musician who credits himself as the world’s premier whistler.
It’s a pretty big claim, when you’re up against Flo Rida…
But he seems to have pulled it off, winning the International Whistler’s Convention in 2004, 2005 and 2008 and now judging the competition.
He said he was inspired by his father, who used to whistle around the house, but I have never heard anything quite like this.
Here he is singing… whistling the Queen Of The Night; make sure you’ve put the dog out!
