Legend invited Underwood to perform the emotional duet of Shelton’s first single with him.

In a 2023 episode of The Voice Coach John Legend’s YouTube show “Trailer Talk,” where he interviews and performs music covers with famous Artists, he brought on Carrie Underwood to sing a classic by Blake Shelton: “Austin.”

The Voice returns on February 26. Catch up on on NBC and Peacock.

In the episode, Underwood told Legend that she would love to hear his voice on a country song, so they decided to sing “Austin.” Of course, Legend’s piano-playing was top-notch, and the two switched back and forth on the vocals, their voices perfectly complementing each other.

Check out their stunning version of “Austin” in a video further down this article. Start around the 8:40 mark.

About “Austin” by Blake Shelton

Released in 2001 off Shelton’s debut, self-titled album, “Austin” was The Voice alum’s first major hit. It reached the number-one position on the Billboard U.S. Hot Country Songs chart, and the lyrics tell the story of a man who leaves a message on his voicemail machine to his ex-girlfriend, reminding her that he still loves her.

She left without leavin’ a number
Said she needed to clear her mind
He figured she’d gone back to Austin
‘Cause she talked about it all the time
It was almost a year before she called him up
Three rings and an answering machine is what she got

If your callin’ ’bout the car, I sold it
If this is Tuesday night, I’m bowlin’
If you’ve got somethin’ to sell your wastin’ your time, I’m not buyin’
If it’s anybody else wait for the tone you know what to do
And P.S., if this is Austin, I still love you

The telephone fell to the counter
She heard but she couldn’t believe
What kind of man would hang on that long
What kind of love that must be
She waited three days and then she tried again
She didn’t know what she’d say
But she heard three rings and then

If it’s Friday night, I’m at the ball game
And first thing Saturday, if it don’t rain
I’m headed out to the lake and I’ll be gone all weekend long
But I’ll call you back when I get home on Sunday afternoon
And P.S., if this is Austin, I still love you

Well, this time she left her number
But not another word
Then she waited by the phone on Sunday evening
And this is what he heard

If your callin’ ’bout my heart, it’s still yours
I should’ve listened to it a little more
Then it wouldn’t have taken me so long
To know where I belong
And by the way, boy, this is no machine your talkin’ to
Can’t you tell, this is Austin, and I still love you

I still love you
