Taped in 1960. They argued through the whole session and nobody stopped the machine.

New York, August 1959.
Dinah Washington and Brook Benton entered the studio to make what should have been a polished duet.
Both could sing beautifully.
Both were established professionals.
But they did not approach recording the same way.
Washington was prepared, precise and fiercely protective of her part.
Benton was relaxed, playful and inclined to improvise around whatever was happening in the room.
That difference became audible during Baby (You've Got What It Takes).
And producer Clyde Otis did something crucial.
He kept the tape running.

As the performance moves forward, Benton begins inserting comments around Washington’s lines.
Then he comes in where she expects to sing.
Washington reacts immediately.
Her spoken warning—telling him that he is back in her spot—is not the kind of perfectly rehearsed exchange normally associated with a carefully produced pop duet.
Benton answers her.
Washington answers back.
Instead of destroying the take, the collision gives the record personality.
What had begun as a romantic duet suddenly sounds like two strong people teasing, correcting and challenging one another in real time.

Accounts of the session describe genuine tension between their working styles, although it is safer to call what survives on the record an unscripted studio collision rather than a furious argument from beginning to end.
Otis understood what mattered.
The mistake made the singers sound human.
So it stayed.
Released in January 1960, Baby (You've Got What It Takes) became enormous.
It reached No. 5 on the Billboard Hot 100 and spent ten weeks at No. 1 on the R&B chart.
The chemistry listeners loved was partly the sound of two performers refusing to disappear politely behind one another.

The ending now feels almost like eavesdropping.
Washington directs.
Benton jokes.
Their voices bump into one another.
And somehow the imperfection becomes the most memorable part of the performance.
Three years after the record became a hit, Dinah Washington died unexpectedly in December 1963 at only thirty-nine.
That gives those spontaneous spoken moments an added weight today.
They were not designed as a final statement.
They were simply two personalities caught on tape.
That is why the recording still feels alive.
Most studio mistakes are removed.
Most arguments disappear when somebody says, “Let’s do another take.”
In this case, the producer heard the tension and understood that perfection would make the record less interesting.
The singers stepped on each other’s lines.

The tape kept rolling.
And the mistake became part of the hit.
