Video: Manny Pacquiao has released this gem of a song for the Mayweather superfight

Manny Pacquaio has released his official song for the Floyd Mayweather Jnr fight.

What's that? You didn't realise that releasing an official soundtrack for a boxing fight was an actual thing? Well, neither did we, but Pac-Man has broken the mould with this one. He does love a good sing song.  We're not entirely sure why he's written it, what it means, or why the hell he is not just concentrating on training to whoop unbeaten Mayweather's ass on May 2nd. But it's out there in the world now so you might as well watch it in all its glory...
