in general it is usually good to play the song and just read across the notes as your hear them that way the rhythms get into your brain and you just have to make the transition to your hands.. play it slow and in rhythm until you can bring it up to speed, this of course wont take you very long as it is indeed a slow song..

however with this song in particular simply knowing your 4 chords that make up the song (G, D, C, Am) you should just need to figure it out with your picking hand as the chord changes are quite simple
