Great Song, it took a long time for me to figure this one out. The other version isnt wrong,
but its just not how they play it and it doesnt go as in depth.
It looks really hard, but it really helps if you listen to the song while you do this. 
Tab is above words, Enjoy!

Stay the way I am today and serve to more disaster
He could tell a fairy tale that's happy ever after
Just relax and green of grass will grow here for a change
