your not going to find specific song tutorials here due to licensing/copyright issues, but you can get the tab (short for tablature - which is a simple way of writing guitar pieces that will have to learn to read) off the internet, GOOGLE!. Then you can try and follow some of the videos on youtube (the song is actually called "good riddance").

While it is a "simple" song, there are still chords and picking patterns that you are going to find frustrating for a couple of weeks...

I would def. recommend that you work your way through the 2 beginners guides on this site along side working through your first song.
