Here's the riff that goes on.  Depending on what you're doing with this
song, you can make octaves or even power chords out of it.  The slide in the
4th measure isn't important, I just think it sounds better.
e|---------------|-------------|---------------|-----------------------|
B|---------------|-------------|---------------|-(the)-(right)-(stuff)-|
g|-------8-7-----|-------8-7---|-------8-7-----|-----------------------|
D|--6-6------8---|--6-6--------|--6-6------8---|---6-----8/10---8------|
A|---------------|-------------|---------------|-----------------------|
E|---------------|-------------|---------------|-----------------------|

Power chords would look like this:
e|---------------|-------------|---------------|-----------------------|
B|---------------|-------------|---------------|-(the)-(right)-(stuff)-|
g|-------8-7-----|-------8-7---|-------8-7-----|-----------------------|
D|--6-6--8-7--8--|--6-6--8-7---|--6-6--8-7--8--|---6-----8/10---8------|
A|--6-6--6-5--8--|--6-6--6-5---|--6-6--6-5--8--|---6-----8/10---8------|
E|--4-4-------6--|--4-4--------|--4-4-------6--|---4-----6/8----6------|

The verse and the "Right Stuff" part, (which I don't feel is a proper thing
to label as the chorus in this song) is just Ab and Bb going back and forth
in half notes.  I tried to be as exact as I could to show where the lyrics
fall in relation to the two chords

THE REST OF THE LYRICS: 

(Verse) Oh Oh Oh Oh, Oh Oh Oh Oh.
Oh Oh Oh Oh, Oh Oh Oh Oh.
The first kiss was a sweet kiss
The second kiss had a twist
The third and your fourth kiss
I don't want to miss
I can see it in you walk
Tell it when you talk
Can see it in everything you do
Even in your thoughts
You got the right stuff baby
I love the way you turn me on
You got the right stuff baby
You're the reason why I sing this song
(Chorus)All that I needed was you
Oh, girl, you're so right
And all that I wanted was you
You made all everyone of my dreams come true
Oh Oh Oh Oh, Oh Oh Oh Oh.
Oh Oh Oh Oh, Oh Oh Oh Oh.
Girl, yeah baby
You know you got the right stuff
Girl, yeah baby
You know you know you got it, girl
In my life, it's so right
You made it.
Oh Oh Oh Oh Oh, Oh Oh Oh Oh Oh the right stuff.
Oh Oh Oh Oh Oh, Oh Oh Oh Oh Oh the right stuff.
