This rendition of Happy Birthday is definitely like nothing you've heard before.
It features cats, dogs, rabbits, rats, horses and even a guinea pig who all make their distinctive noises to the tune of the classic birthday anthem.
The track and its super cute video were put together by the Blue Cross especially for the animal-loving Queen's 90th birthday. And we're sure she'll agree it's oddly fascinating to listen to.
Its stars are some of thousands of rescue pets from the charity's rehoming centres across the UK. (Though after seeing their tuneful talent, hopefully they won't be there for too much longer.)
