Reagan Services's 'Mansions of the Lord' Friday was a national day of mourning across the U.S., culminating in the removal of President Reagan's casket from the Rotunda of the U.S. Capitol building, its transport through Northwest Washington, D.C. to the National Cathedral, and the state funeral service. The service was an event of unparalleled grandeur. All four ex-Presidents and their wives were present, along with President and Laura Bush, members of the Cabinet and U.S. Supreme Court, and many heads of state, including British Prime Minister Tony Blair. There were also quite a few musicians in the cathedral, and they provided a moving accompaniment in music to the funeral service. We take you inside the cathedral during Friday's service for some of that music. First the hymn, "O Love of God, How Strong and True," also known as "Jerusalem," followed by another hymn, "The Mansions of the Lord." The U.S. Armed Forces Chorus and the U.S. Marine Chamber Orchestra perform. Our expanded coverage includes on-demand audio of the music.
