President Barack Obama got onstage to perform with country music star Willie Nelson during a concert honoring the U.S. troops, “A Salute to the Troops: In Performance at the White House.”

Nelson, 81, opened the concert, which aired on PBS Friday, Nov. 7, with “We Don’t Run,” and was joined onstage by John Fogerty, Common and President Obama to perform “On The Road Again.”

Willie Nelson Sings Duet With President Obama

Obama introduced Nelson and was about to head off stage when Nelson tapped him on the shoulder and instructed him that he would have to sing along. “Willie Nelson says I’m going to have to sing with him, so I’ll try it out,” Obama announced to the crowd of servicemen and women.

The concert also featured performances by members of the Armed Forces and Mary J Blige. “We’ve got a little bit of rock-and-roll, we’ve got a little bit of country, a little bit of everything in between. And that’s good, because here in America, no matter where you are from, no matter what music you listen to, we’re all united out of respect and admiration for the brave men and women who wear our country’s uniform,” Obama said in his opening remarks.
