I started playing this tune here which I have learnt from a youtube video by Mike Herbert.
I can play it, though not so smoothly yet when I need to change chords. I am still struggling with my chord changing, but I know I am getting better. Learning to play this way is so addictive. Instead of strumming a chord or two you get bored. But when you learn to make a rhythm you find yourself trying hard to get it right. Well in my case at least.
Mike Herbert is a great teacher. He has a website at http://www.6-string-videos.com where you can subscribe to his newsletter and receive 48 video lessons for FREE! Not one short though but every few days.
If you want you can buy the dvd from him. If you don't buy, it's still fine with him too. Well, that's what he said though, not me. If I get better playing my guitar with his lessons, I don't mind to buy from him later to tell frankly.
Anyway, if you are thinking of learning or picking up the guitar again, you should check his videos. :)
