Country singers Garth Brooks and Trisha Yearwood paid tribute to late President Jimmy Carter at his funeral by performing a rendition of John Lennon's "Imagine." The couple harmonized while Brooks played the acoustic guitar, with the funeral choir providing background vocals. The performance was a rare public appearance for the couple since Brooks faced sexual assault allegations, which he has denied. Brooks and Yearwood had a close friendship with the Carters through Habitat for Humanity projects, and they honored the former president's legacy of service at the funeral.
