Melodies sung by voice can be complicated to transcribe to piano. Concentrate on 'chest' in the second measure. It's not a g, not an f either.
It's a g and an f, I thought. But what the singer does with his voice, can't be translated to a piano. He slides from the g to the f.
So what to play? I don't like the g plus f as notated above. You get the first measure repeated, while it doesn't seem two times the same in the song, because 'chest' is one syllable.
It will be one note, an f. Though it's not quite right, the result on piano is better.
