The Grateful Dead – Don't Mess Up A Good Thing (Live, Fillmore Auditorium, San Francisco, July 3, 1966)

You’ve been cheating on me, uh-huh
You know my love is true
Ain’t nobody in the whole wide world
Gonna love you like I do

Chorus

Well, don’t you be no fool
Don’t you be no fool
If you keep messing around now, baby
You gonna mess up a good thing
You gonna mess up a good thing

Verse 2

I’m might have cheated just a little bit, baby
Like all the others do
Ain’t about time to get my check
Now I rush right home to you

Chorus

Now don’t you be no fool
Oh, don’t you be no fool
If you keep messing around now, baby

(A good thing)
Gonna mess up a good thing
(A good thing)
You don’t know what you’re hitting
(A good thing)
Gonna mess up a good thing
(A good thing)
Na-na-na-na-na

Verse 3

You tell me that you got a part-time lover
Living away across town
It won’t be just about little while, baby
Before you put mе down

But don’t you be no fool
Oh, don’t you be no fool
If you keep messing around now, baby
You’rе gonna mess up a good thing
You’re gonna mess up a good thing

Verse 4

Now don’t you go running across town, baby
To catch me doing wrong
I’m just a little bit jealous, baby
‘Cause we got a thing going on

Chorus

But don’t you be no fool
Oh, don’t you be no fool
If you keep messing around now, baby
You’re gonna mess up a good thing
You’re gonna mess up a good thing
