The former president will be laid to rest Thursday following almost a week-long celebration of his life.
Reba McEntire was overcome with emotion while performing the "Lord's Prayer" at George H.W. Bush's funeral on Thursday.
Shortly after singing the opening lines, "Our Father who art in Heaven," the country legend stopped to cough and regain her composure.
McEntire, 63, stopped in front of a weeping George W. Bush, who wiped his face with a cloth, for part of her performance.
She was able to sing the rest of the tune without issue until the very end, when her voice almost broke as she sang, "Give us this day."
