This is without doubt one of the best country rock songs ever written and
always gets unexpected praise when I play this song live. I prefer using the
capo on the 3rd fret as this makes the chord progression closer to the vocals (mine at least).

(capo 3rd)

Intro  D / / F#m / / Am / / B7 / / D
D                  F#m                    Am                    B
You may be, sweet and nice, but that won't keep you warm at night
Em                     Em(+Maj7)                 Em7               A
Cuz I'm the one, who showed you how, to do the things you're doing now
D           F#m               Am                 B7
He may feel, all your charms, he may hold you in his arms
Em              A7           Em           A7                   D
But I'm the one, who let you in, I was right beside you then  

G             Gm               D              Bm
Once upon a time, you let me feel you deep inside
E              E7            G                          A
and nobody knew, nobody saw, do you remember the way you cried

D             F#m
I'm your toy, I'm your ol' boy
Am             B7                                Em
And I don't want no one but you to love me
                A   Em                     A          D          
No, I wouldn't lie, you know I'm not that kind of guy
