The original key is in F#, not G... so as a guitarist you'll want to drop
tune down a half step. On a piano it's way easier to play in F#, and this
song sounds better in F#, so the tuning should be down a half step.

This was a bit difficult to transcribe because for one his voice is loud and
it's hard to hear the piano, and it sounds like he's using a lot of 
non-chord tones. That said, listen to the song while playing it to try to 
get some of those non-chord tones he's using, as well as his positioning. It
also seems like he's using a lot of open fifths, something to be mindful of.

I'm sure this isn't perfect, so if someone has a better ear for it there 
might need to be some corrections!
