AP PHOTOS: Girls will be part of St. Paul's Cathedral choir on Christmas Day for first time

For the first time in its 900-year history, girls will form part of the choir performing at the Christmas Day service on Wednesday at London’s majestic St. Paul’s Cathedral. The choir, which is made up of both adult and child choristers, will perform at services on Christmas Day under the 365-foot (111-meter) dome of the cathedral, designed by architect Christopher Wren after the 1666 Great Fire of London destroyed its medieval predecessor and much of the surrounding old city. The first two girls to become full choristers officially joined the choir in June.
