It really annoys me how many people have tabbed this simple song and got it wrong - I
came across 5 versions on TabCrawler alone, in several different keys! Here is my
interpretation - I'm pretty sure I'm the right key (F minor if you're interested)...
Don't forget to tune your bottom E string to D for the chorus section!
