I LOVE this song and when I saw that the chord chart wasn't on here, I thought 
that it was about time to get on that. So here you go! Please do enjoy. Also, for 
the Am, I use an Am7, mainly because I think it sounds more appropriate, but both 
Am and Am7 work. It's really just up to your own judgment.
