Michael Bubl performed a private concert of Christmas songs for a trio of gorillas

The lucky apes Ganyeka, Yakini and Motaba currently live at the Werribee Open Range Zoo in Melbourne, Australia. According to PRI, one of the zookeepers discovered that the silverback gorillas responded quite positively to Bubl's dulcet tones:

When we play Michael Bubl's CDs, the boys will instantly start pleasure grumbling and sit nice and calm and relaxed. Our theory is its the beautiful low tones that he sings with kind of mimics their pleasure grumble. And theyve even been shown to hum little food songs when they eat, and we think [Bubl] must really resonate with that sound.

So as long as Bubl was in Australia anyway, they got him to stop by the zoo and surprise the silverbacks with a little private croon.
