LONDON, (AFP) — Prince Harry celebrated his 30th birthday Monday with a beer after the closing concert of his inaugural multi-sport event for wounded troops, and in the knowledge he will now receive a fortune from his late mother Diana’s estate.

Harry, fourth in line to the British throne, can put his feet up after organising the four-day Invictus Games for injured veterans, which was deemed a success.

As the Games closed, 26,000 revellers chanted the prince’s name.

As he enters his fourth decade, a beer for Harry these days is more likely the reward for a job well done rather than a prelude to the sort of high jinks that had senior royals cringing when he was in his early 20s.

But there is still an element of royal rebel about Prince Henry of Wales — it is hard to imagine too many members of the House of Windsor appearing on stage at a rock concert in a fleece jacket and jeans, launching a Mexican wave and embracing long-haired rockers as Harry did Sunday.

An army captain who served two tours in Afghanistan, Harry has taken the cause of wounded service personnel to his heart, and said a successful Games would be his birthday celebration.

The ginger-haired prince is still a bachelor after breaking up with girlfriend Cressida Bonas in April, though the society beauty was spotted in the crowd at the concert lending her support.

Anticipating the birthday milestone, Harry said: “On the birthday side of things, I’ll be chuffed to bits when I’m having a beer with Dave Henson, captain of the Team GB — we turn 30 at exactly the same time, on Sunday night.

“We’re really looking forward to being 30, both feeling quite old about it.”

He said he would feel a sense of mission accomplished when the 400-plus competitors from 13 nations were taking their flights home Monday with smiles on their faces.

“It kept me out of the office, kept me off a desk job,” he told BBC television.

After the strains of flying Apache attack helicopters in Afghanistan in 2012-2013, Harry’s job now is to organise commemorative army events in London.
