Played live by the Grateful Dead in their very early days in 1966
You been cheating on me
You know my love is true
Ain't nobody in the whole wide world
Gonna love you like I do
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
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 it home to you
Don't you be no fool
Don't you be no fool
If you keep messing around now baby
(Good thing)
Gonna mess up a good thing
(Good thing)
You don't know what you're hitting
(Good thing)
Gonna mess up a good thing
(Good thing)
Na na na na na
You tell me that you got a part-time lover
Living away cross town
But it won't be just about little while baby
Before you put me down
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
(Good thing)
Gonna mess up a good thing
(Good thing)
You don't know what you're hitting
(Good thing)
Gonna mess up a good thing
(Good thing)
No no no no no
