In early December, a plethora of musical stars gathered in New York City to celebrate John Lennon, for what would have been the musical icon’s 75th birthday. On Saturday night (Dec. 19), the concert aired on AMC, including a performance of "Imagine" by none other than Willie Nelson.

Standing at center stage, in front of a screen showing the "Imagine" mosaic memorial to Lennon in Central Park's Strawberry Fields, Nelson sang a simple version of the famous song. His backing band included a harmonica player who, along with Nelson's strumming on his trusty guitar Trigger, added a country flavor to the musical plea for peace. Press play on the video above to see the country legend's performance.

Also in the lineup for Imagine: John Lennon 75th Birthday Concert were Eric Church and Chris Stapleton, along with Aloe Blacc, Sheryl Crow, Peter Frampton, Juanes, Kris Kristofferson, Pat Monahan, Tom Morello, the Roots and Steven Tyler.

“It’s beautiful to see so many wonderful and talented musicians come together for this special show to celebrate John’s birthday,” says Lennon’s widow, Yoko Ono. “John’s art continues to give hope, light and happiness to generations of people everywhere. His belief that each of us can change the world continues to inspire the human race to believe in themselves, and his influence is everlasting in everyone’s hearts as we all share in the possibilities and power of music.”

Lennon was born on Oct. 9, 1940, in Liverpool, England. He was shot and killed in New York City, at 40 years old, on Dec. 8, 1980.
