Yes, it was the Cadets.

I crashed in the jungle while trying to keep a date,
With my little girl who was back in the States.
I was stranded in the jungle, afraid, alone,
Trying to figure a way to get a message back home.
But how was I to know that the wreckage of my plane
Had been picked up and spotted, and my girl in Lover's Lane?

And meanwhile, back in the States...

Baby, baby, let's make romance.
You know, your old-time lover hasn't got a chance.
He's stranded in the jungle, glad as he can be.
So come on, pretty baby, just you and me.

Meanwhile, back in the jungle...

The boys in the jungle had me on the run,
When something heavy hit me, like an atomic bomb.
When I woke up, and my head started to clear,
I had a strange feeling I was with cooking gear.
I smelled something cooking, and I looked to see.
That's when I found out they was cooking me.

And meanwhile, back in the States...

Baby, baby, let's make romance.
You know, your old-time lover hasn't got a chance.
He's stranded in the jungle, glad as he can be.
So come on, pretty baby, just you and me.

Meanwhile, back in the jungle...

I jumped out the pot, and I finally got away,
Frantic and worried about what my baby would say.
So I jumped in the ocean and started to swim,
But my chance of survival was getting mighty slim.
So, I thumbed down a whale who was in my way,
And I reached the States in about a half a day,
And when I got to Lover's Lane, I was almost dead,
But my soul was gone, and here's what I said:

Baby, baby, the man is no good.
Oh baby, baby, you should have understood.
You can trust me as long as you please,
So, come back pretty baby where you used to be.
'Cause I love you,
'Cause I love you [repeat and fade]

Apparently some upstart whippersnappers named the Nylons also recorded it, which may be the 70's(?) version you were thinking of.
