This tab is 100% correct. I pulled it from the original songbook of "Verities &
published in 1974. It tooks me two years to find this book, and I bought it just for this song. 
luck!

(The rest of the song is played in the same pattern. VERSE 3 has the same chords as 
1, VERSE 4 and VERSE 5 have the same chords as VERSE 2, and the CHORUS chords are all the same.)

VERSE 3
So I tried to teach her a couple of chords
and an easy melody;
but it always turned out she'd rather listen
to my guitar and me.
I could hear her old man laughing in the den,
playing stud poker with the boys
while I sang so soft in the living room,
to scared to make much noise.

VERSE 4
I came one week and the den was dark
and she met me at the door.
And we sat on the couch and we sang and talked
till I could not sing no more.
The silence kept on building,
her eyes grew much too wide;
and I could her both of our heartbeats,
but there was no place to hide.

CHORUS
         G (320003@1)                        Am7She (x02010@1)said, "I wanna learn a love song full of happy things."
         D (xx0232@1)                                    CShe (x32010@1)said, "I wanna learn a love song; won't you let me hear you sing?"
            G (320003@1)                     Am7She (x02010@1)said, "I wanna learn a love song, I wanna hear you play."
            D (xx0232@1)                        C (x32010@1)     Am7 (x02010@1)GShe (320003@1)said, "I wanna learn a love song before you go away."

VERSE 5
Well, I guess you know what happened,
God, I never been so clean.
Yes, I feel like I'm working in a Hollywood movie
or living out a good bad dream.
And all them pinup girls in that tinsel world
never touched me like she can;
it took another man's wife in the real world life
to make this boy a man.

CHORUS
         G (320003@1)                        Am7She (x02010@1)said, "I wanna learn a love song full of happy things."

            G (320003@1)                     Am7She (x02010@1)said, "I wanna learn a love song, I wanna hear you play."
