On "Fox & Friends" Friday morning, country music star John Rich shared a story about a memorable exchange he had with George H.W. Bush.

The 41st president of the United States passed away last week at the age of 94. Bush is to be interred Friday on the grounds of the George H.W. Bush Presidential Library and Museum, on the Texas A&M University campus, near his wife, Barbara, and Robin, their daughter who died of leukemia at the age of 3 in 1953.

Rich, of the duo Big & Rich, recalled when he recorded a special performance of his song "The Good Lord and the Man" for Bush in 2009 to wish him a happy 85th birthday.

Bush listening to the song -- and his touching response to Rich -- was captured in outtake footage from an HLN interview.

"John, this is George Bush," the former president said in a voicemail to the country singer. "I'm very touched by it. I love your music and I love this song particularly, so you're guaranteeing me a happy 85th birthday."

Rich explained to the "Fox & Friends" hosts that he chose that particular song because it is about his own grandfather, a veteran of World War II, just like Bush.

"The song honors World War II vets, the Greatest Generation. It says it it wasn't for the Greatest Generation and the ones still fighting for our nation, because of that I've never had to kill for my way of life," Rich said. "Those guys literally saved the world, and now we've got guys and girls out there fighting for the American Dream."

"We have a lot of respect for them in country music, and we write songs about them."
