Hmm, I found a CD with the song on it. Claims to be the original recording. Much simpler lyrics:

Come And Go With Me The Dell Vikings

Dom dom dom dom dom
Dumby dooby
Dom dom dom dom dom
Dumby dooby
Dom dom dom dom dom
Dumby dooby dom
Wa-wa-wa-wa-ah

Dom dom dom dom dom
Dumby dooby
Dom dom dom dom dom
Dumby dooby
Dom dom dom dom dom
Dumby dooby dom
Wa-wa-wa-wa-ah

Well, I love you, darlin',
Come and go with me,
Please don't send me
Way beyon' the sea.
I need you, darlin',
So, come go with me.

Come, come, come, come,
Come into my heart.
Tell me, darlin',
We will never part.
I need you, darlin'
So, come go with me.

Yes, I need you, yes, I really need you
Please say you never leave me.
Well, say you never
Yes, you really never
[BASSO] Never give me a chance
[FALSETTO: ohhh]

Come, come, come, come,
Come into my heart.
Tell me, darlin',
We will never part.
I need you, darlin'
So, come go with me.

[SHOUT] Yeah!
[INSTRUMENTAL BREAK]

Yes, I need you, yes, I really need you
Please say you'll never leave me.
Well, say you never
Yes, you really never
[BASSO] You never give me up
[FALSETTO: ohhh]
[BASSO] Up, Up

I love you, darlin',
Come and go with me,
Please don't send me
Way beyon' the sea.
I need you, darlin',
So, come go with me.
Come on, go with me.
Come on, go with me.
Come on, go with me.

Given the non sequiter of the bass's line before the break and the extreme amount of repetition in and between verses, I can easily believe that it was 'shined up' after the version I have.

P.S. Anybody got parts for it? The melody line is easy enough to pick out, but I'm having one hell of a time trying to sort out the 'tunes' for the three other voices. Bass ain't TOO bad, but the other voices are just not separable.
