Bluey Robinson. If you don't know who this guy is then you should SLAP YOURSELF (not to hard, just hard enough to feel ashamed for the serious British talent you've been missing out on!).
I first heard of this guy when I went to a Tinie Tempah concert last October (I got splashed in the face with a bottle of water but it was totally worth it!). Since then he's gone on to collaborate with Tinchy Stryder, perform with Ryan Leslie and tour with Justin Bieber.
This is an acoustic version of his song 'Showgirl', oh and did I forget to mention the fact that he's gorgeous, but I'm sure you would have worked that out for yourself. :)
