Michael Bublé performs a private gig for a bunch of gorillas. Seriously.

While most people refer to a group of gorillas as “troop,” it’s also acceptable to use the term “whoop.” That might have been the reaction of Ganyeka, Yakini and Motaba, three primate inhabitants of the Werribee Open Range Zoo, which is south of Melbourne, Australia.

Apparently, this troop/whoop really enjoys the music of Michael Bublé. In fact, they really appreciate it when their caregivers play them Bublé’s Christmas album year-round.

When Bublé heard about this, he decided to not only pay them a visit but to also give them a private concert.
