This is a really short theme song for Kure Kure Takora, aka Gimme Gimme Octopus, a Japanese children's TV series about an octopus and a peanut who are in love with a walrus. Japanese mariachis play the theme song and the octopus plays air guitar. I always imagine the Japanese man singing this has rubber all over his face.
