Thursday's funeral service in Houston was held at St. Martin's Episcopal Church, where Bush and former first lady Barbara Bush worshipped for more than five decades, and took on a more personal tone with remarks by family members.

George W. Bush, who followed his father to the White House after President Bill Clinton's two terms, sat in a front pew near the flag-draped casket and joined in as some 1,000 mourners sang "America the Beautiful."

George P. Bush, son of former Florida Governor Jeb Bush and one of the former president's 17 grandchildren, remembered fly fishing and sharing ice cream with the man he called "Gampy."

James Baker, a longtime friend who served as Bush's secretary of state, eulogized the former Republican president as a peacemaker and "a truly beautiful human being."
