Throwback to 2003 when Shania Twain joined Willie Nelson for an iconic love song duet

Fifteen years ago, singers from different genres came together for Willie Nelson's 70th birthday. From all the performances that evening, one stood out.

Shania Twain, who was 38 years old at the time, took to the stage with Nelson to give one of her most moving performances to date.

Kris Kristofferson introduced her to Nelson, and they performed Blue Eyes Crying In The Rain. The song was from Nelson's album, Red Headed Stranger.

She was dressed in a Willie Nelson t-shirt and wore a pair of jeans and grey cap for their iconic duet. His birthday bash was broadcasted to fans across the world.

The track was written by Fred Rose in the forties and had also been performed by other veteran musicians such as Elvis Presley and Roy Acuff.

It was the same song that launched Nelson's singing career in the mid-seventies. Before Nelson soared to fame, he worked as a songwriter.

Some of his successes as a songwriter was Crazy, performed by Patsy Cline. He also wrote Pretty Paper for Roy Orbison and Funny How Time Slips Away for Billy Walker.

He produced his first record, No Place For Me, in the late fifties but didn't receive positive reviews for it. Instead, he plied his craft as a radio announcer and club singer.

Today, Nelson is considered to be an American Icon and have throughout his career received a slew of awards, including the Kennedy Center Honors in the late nineties.

He was inducted into the Country Music Hall of Fame when he turned 60. In 2013, Nelson celebrated his 80th birthday in style once more, and the prestigious event was held at Third Man Records in Nashville.

Nelson produced 67 albums, and his latest album, Last Man Standing, was released in April 2018 by Legacy Recordings.
