The gala concert kicks off at Buckingham Palace this evening with Sir Elton John, Sir Paul McCartney, Dame Shirley Bassey, Sir Cliff Richard and Sir Tom Jones heading the line-up, along with younger artists. Afterward, more than 4,200 beacons are to be set alight in Britain and abroad to celebrate the Diamond Jubilee. One beacon is to be lit in Kenya at the Treetops Hotel, where Elizabeth was informed of her father’s death in 1952, making her the queen.
