Paul Simon - Slip Sliding Away tab

I wanted to learn this song, but couldn't find any accurate tabs. So I worked it out.
This is my first tab, but it sounds right playing along with the song.

Play with Capo on 1st fret.

Intro/Chorus:

              G                 Em
Slip sliding away, slip sliding away
              G                D          C             D       G
You know the nearer your destination, the more you slip sliding away

Verse:
                   Em                    G
Whoah and I know a man, he came from my hometown
             C              D                   C       C7
He wore his passion for his woman like a thorny crown
         G                 Em
He said Dolores, I live in fear
             G              D            C           D        G
My love for you's so overpowering, I'm afraid that I will disappear

Chorus x1

I know a woman, (who) became a wife
These are the very words she uses to describe her life
She said a good day ain't got no rain
She said a bad day is when I lie in the bed
And I think of things that might have been

Chorus x1

[F to C then back to G]

And I know a father who had a son
He longed to tell him all the reasons for the things he'd done
He came a long way just to explain
He kissed his boy as he lay sleeping
Then he turned around and he headed home again

Chorus x1

Whoah God only knows, God makes his plan
The information's unavailable to the mortal man
We're workin' our jobs, collect our pay
Believe we're gliding down the highway, when in fact we're slip sliding away

Chorus x2

Then play G and Em for a while and end on Em
