As the world was awaiting the first glimpse of Britain's new prince on Tuesday, The Queen's Guard played 'Congratulations' during the daily Changing the Guard parade atBuckingham Palace.
Dressed in traditional red tunics and bearskin hats, the Guardsmen paid tribute to the new addition to the royal family during the ceremony.
The Duke and Duchess of Cambridge have spent the night with their son after Kate, 31, gave birth to the couple's first child, who is third in line to the British throne, on Monday afternoon, ending weeks of feverish anticipation about the arrival.
The popular couple were expected to adhere to tradition by giving the public the first sight of the royal baby on the steps as they leave St Mary's Hospital in west London - just as William's father Prince Charles and late mother, Princess Diana, did with him.
