This is a guess by ear. I'm absolutely NOT sure this is right, but I coulnd't find any
tab on the net. Also, most of the lyrics are absolutely wrong, but I couldn't find the
lyrics either and I'm not a native anglophone, so i hope you'll forgive me for that. The
lyrics I put are just to give an idea.
The chord at the end of every verse could as well be Gmaj7 or G6, they all sound acceptable.
If you are a beginner, you may want to transpose it in G (+5 or -7, it's the same) to 
eliminate the barr?s, and maybe put a capo on 7th fret.
