This is an old rock song in the Philippines, entitled 'Banal na Aso' ,translated, it literally means 'Holy/Pious Dog' ..the song itself talks about hypocrisy/biases of some people.
The singer in this video who calls himself Big Mouth did this cover and made the song even more entertaining with his remarkable voice mimicry of animal sounds.
The first few lines of the song goes..Banal na Aso, Santong Kabayo..natatawa ako...it means Holy Dog, Saintly Horse, so amusing/funny and then he lets out a very convincing horse mimicry sound.
