Country Music Hall of Fame group The Oak Ridge Boys joined Dana Perino Monday on "The Daily Briefing" to reflect on their relationship with George H.W. Bush, who died Friday at the age of 94.

A funeral service for the 41st president will be held on Thursday, Dec. 6, at St. Martin’s Episcopal Church in Houston, Texas.

Group member Duane Allen told Perino that the group's relationship with Bush 41 began when they were performing at a White House barbecue for President Ronald Reagan, for whom Bush served as vice president.

Allen said that Bush approached them and said he was a big fan, asking to be played songs that weren't singles or as well-known.

"So we did a private concert for him on the White House lawn in the afternoon during sound check," he said.

Richard Sterban added that with Bush in the White House, he further mainstreamed country music.

"We're so grateful to him for doing that," he said.

The group is set to sing "Amazing Grace" at Bush's funeral on Thursday, and Allen said he requested for them to be there.

"To the Oak Ridge Boys, I just gotta say, we loved him dearly," Joe Bonsall said.

"Him and Barbara Bush made us better people, better Americans. We're gonna sing for him Thursday, it's gonna mean a lot to us to do that. And I'll be honest with you -- it's not the last time we'll sing for him."
