Queen Elizabeth II celebrates her 83rd birthday Tuesday, which will be marked by a 41-gun salute in central London.

The monarch is expected to spend the day at Windsor Castle, her favourite residence just west of London, with husband Prince Philip.

God Save the Queen Lyrics (standard version)

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.

O Lord, our God, arise,
Scatter her enemies,
And make them fall.
Confound their politics,
Frustrate their knavish tricks,
On Thee our hopes we fix,
God save us all.

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