According to BBC News:
A Royal Marine from Devon will lead 468 servicemen in front of the Queen and Prince Philip in the final performance of a 34-year military career.
James Whitwham, from Ivybridge, will front the biggest ever Beating Retreat in London in June.
The bi-annual event will also feature musicians from the United States Marine Corps and the Royal Netherlands Marine Corp.
Beating Retreat is performed every two years in celebration of the birthday of Prince Philip, Captain General of the Royal Marines.
This year’s event also marks the 350th anniversary of the Royal Marines.
