The true version of this was written and performed by Makana. It was the theme tune to the excellent George Clooney film The Descendants. 

Those of you familiar with Makana's work will realise that this rendition is not musically accurate. His is performed in Hawaiian 'slack' guitar tuning. As a live performer I don't have the time to re-tune my guitar and so decided to create my own version attempting to keep the original essence of the work as much as possible. I just had to have this in my set and couldn't bare to leave it out.

Sorry to Makana for not being able to do his music full justice.
