Prince George held his hand over his ear as trumpeters lined out at the back of the chapel to herald the arrival of Eugenie.
The future king was standing next to sister Princess Charlotte and Peter and Autumn Phillips’ daughter Savannah.
As the trumpeters got in position, the nanny held George and Charlotte’s hands.
Before that, George could be seen looking around the chapel and craning his neck to look up into the high ceiling.
The prince could be seen shuffling his feet on the carpet beneath him, while Charlotte went up on her tiptoes at one point.
The group of children were startled and jumped when the trumpeters performed an initial flurry, and Savannah appeared to put a finger in her ear as she anticipated what was to come.
At one stage, George seemed to shake his legs and briefly bobbed up and down in time to the music.
In the few minutes the children had to stand, one little girl appeared to sit down on the stone ledge behind them before the nanny nudged her up.
