Every time this commercial comes on I have to turn up the t.v. volume. I love this song. Don't ask me what the guy is singing about, it doesn't matter. It get's my serotonin pumping and makes me happy every time I hear it. It wasn't hard to "google" the song, it's "Jan Pahechan Ho", sung by Mohammed Rafi in 1966. Kudos to Heineken for choosing an awesome song to a memorable commercial.
