Lee Ryan has a really nice voice, which, coupled with his broad range, great vocal technique and an amazing ability to express his emotions through his singing, amount to AWESOMENESS ♥. I love how he sings this song; it sounds very raw, very heartfelt and it's just totally gorgeous guhhh. And if you thought it wasn't humanly possible, he performs (1 2) even better than the recorded version *___*! He took part in writing this song, by the way.
Well, Lee is awesome by definition, if only because he co-wrote and totally owned Breathe Easy, which happens to be one of my favourite song of all time x).
