Her Majesty announced music as the theme for the day, saying it was a bond which "all the young people of the Commonwealth will share together''.

She added: "Throughout our 54 countries, people will be celebrating and making music in as many ways as that, or more.

"Of course people of different generations or cultures tap their feet to quite different beats. But for all of us, young and old, music is an essential part of life -- for parties and entertainment, for ceremonies and celebrations.'' The Queen said today marked the 50th anniversary of the modern Commonwealth, with India becoming the first republic to join in 1949.

"That paved the way to membership for many other countries, especially from Asia and Africa, all sharing links of history, a belief in democracy and a will to work together,'' Her Majesty added.

She said she looked forward to mixing with leaders at November's Commonwealth Heads of Government meeting in South Africa.

The Queen added: "I look forward to joining them there as they discuss the challenges of the new millennium as well as celebrating the Commonwealth's achievements in its life so far.

"Let us then, in this anniversary year, look backwards as well as forwards as we mark Commonwealth Day. While we continue to enjoy our favourite music, either by making it or listening to it, let us also celebrate the vigour and creativity the next generation will bring.

"That is just one of the bonds that all the young people of the Commonwealth will share together on this special day.''
