When [lastfm link_type="artist_info"]Rihanna[/lastfm] and [lastfm link_type="artist_info"]David Guetta[/lastfm] got together to do “Only Girl In The World” I bet they had no idea that someone would take the song to a new level by doing the entire song a capella.  What’s crazier is that if you didn’t see the guy you would have no idea  that he was every instrument and not just the singer, see it for yourself your eyes and your ears are in for a treat!

The guy is only using his voice and his mouth!
