The "lyrics" to this consist of a Pigpen rap that varied a bit from performance to performance. This is the (studio) version from "So Many Roads":
I went down to see a gypsy woman
Wanna find out, oh, what's wrong with me
I said please, please, please tell me now
What's wrong with me
Well she looked at me and she said "Man"
She said "Man, all you need"
All you need, all you need, all you need
All you need is a mojo hand
All you need a mojo hand
That's what I'm gonna do
Get myself a mojo hand
And everything will be all right
