SINGER-SONGWRITER AND MUSICIAN.

HE'S NOMINATED FOR HIS FIRST GRAMMY FOR "SONG OF THE YEAR."

WE'RE SO EXCITED TO HAVE HIM WITH US.

PLEASE WELCOME THE SINGULAR THE DASHING, JP SAXE!

( CHEERS AND APPLAUSE ) SO GOOD TO SEE YOU AGAIN.

NOMINATED FOR YOUR FIRST GRAMMY FOR SONG OF THE YEAR, THIS IS

HUGE, IT IS A MASSIVE CATEGORY.

TALK ME THROUGH, WHAT WAS YOUR REACTION WHEN YOU HEARD?

>> WELL, I WAS EXTREMELY EXCITED.

IT WAS THE LAST SONG NAMED IN THE LAST CATEGORY IN WHICH WE

WERE ELIGIBLE.

SO JULIE AND I WERE WATCHING THE NOMINATION BROADCAST, AND BY

THIS POINT WE JUST ACCEPTED WE WERE BEING VERY OPTIMISTIC,

OVERLY AMBITIOUS, WHY ARE WE EVEN WATCHING THIS.

THEN THEY CALLED OUR SONG NAME AND WE LOOKED APT EACH OTHER IN

SHOCK.

I THINK WE KISSED BUT IT WAS NOT VERY GOOD BECAUSE IT WAS TOO

ENTHUSIASTIC.

A MOMENT LIKE THAT.

WE WERE OVERJOYED.

WE CALLED OUR PARENTS.

IT WAS A REALLY BEAUTIFUL MOMENT.

>> James: THE SONG YOU'RE PERFORMING TONIGHT, "LINE BY

LINE," IS WITH MAREN MORRIS.

HOW DID THIS COLLABORATION COME ABOUT?

>> I TWEETED HOW MUCH I LOVED MAREN MORRIS' SONGS.

I DIDN'T SEE HER SEEING THAT TWEET AS A POSSIBILITY, BUT SHE

DID AND SHE RECIPROCATED THAT SHE LIKED MY SONGS, TOO, SO I

GOT ON A FLIGHT TO NASHVILLE AND WE GOT IN A ROOM TOGETHER, SPENT

TWO DAYS WRITING SONGS, THIS IS THE SECOND ONE WE WROTE.

>> James: THAT'S GREAT.

I'M SO HAPPY YOU DID, AND CONGRATULATIONS ON EVERYTHING,

AND BEST OF LUCK FOR THE GRAMMIALS.

>> THANK YOU.

>> James: LADIES AND GENTLEMEN,

HERE MAKING THE TELEVISION DEBUT OF THEIR BRILLIANT SINGLE "LINE

BY LINE," PLEASE WELCOME JP SAXE AND MAREN MORRIS!
