Rule Britannia, Britannia rule the waves

On official occasions, only the first verse is usually sung, as follows:
God save our gracious Queen!
Long live our noble Queen!
God save the Queen!
Send her victorious,
Happy and glorious,
Long to reign over us,
God save the Queen.

An additional verse is occasionally sung:
Thy choicest gifts in store
On her be pleased to pour,
Long may she reign.
May she defend our laws,
And give us ever cause,
To sing with heart and voice,
God save the Queen.
