The old, funtime Prince Harry played it perfectly for his US audience

It was the old Prince Harry that we all know and love, game for a laugh and happy to send himself up.

Larking about with US chat show host James Corden on an open top bus tour through Los Angeles, there is no denying Harry’s first interview since leaving the Royal family was 17 minutes of TV gold.

From the revelation that the Queen gave her great-grandson Archie a waffle maker for Christmas to the sixth-in-line to the throne rapping the Fresh Prince of Bel Air theme tune, it was pitched as light entertainment.

But it soon became apparent that the carefully-choreographed recording had a much heavier agenda than casual chit-chat over tea and scones.

Borrowing boldly from the Hollywood playbook of mixing business with pleasure, the megabucks deal the Sussexes signed with Netflix last September came along for the ride as Harry extolled the virtues of The Crown.

Most of his relatives have been so offended by its depiction of the Royals as gin-swilling sociopaths that they have refused to watch it, but not seemingly, the Queen’s grandson, who prefers it to “the stories written about my family, or my wife or myself".

I’m not quite sure Prince Charles would agree, but then again, he’s not the one paying the bills any more.

While next Sunday’s 90-minute Oprah special is largely focusing on Meghan, with a side order of Harry, this was about serving up a slice of Montecito monarchy to an eager American audience. Hence the rather laboured references to Royals not carrying cash or travelling on buses, which the Yanks lap up as greedily as episodes of Downton Abbey.

Yet the Duchesses’ presence could still be felt throughout the sympathetic Q and A as “Haz” insisted: “We never walked away” and described how their relationship had gone from “zero to 60” in the first two months.

Selflessly taking one for the team, Meghan then popped up on FaceTime, a seemingly spontaneous moment that just so happened to coincide with her latest blow dry.

Even her husband appeared astonished when Mr Corden had the audacity to refer to the former Suits star as “love” in a slightly cringe moment that only served to remind UK viewers that both men will always carry the “Brits abroad” badge in a place like California.

The former Army captain appeared most at home on the assault course with Corden, enthusiastically encouraging The Late Late Show presenter over various obstacles.

Whether it was supposed to be a metaphor for hurdles Harry has had to jump to “find freedom”, we’ll never know.

But what is clear is that the tell-all will now set the tone for the Sussexes’ future forays into the spotlight as they attempt to rewrite the history of their departure from the Firm through the medium of philanthropy and self-promotion.

By conveniently making no mention of their desire to “work to become financially independent”, as stated in their original ‘Megxit’ bombshell of Jan 8 last year, Harry made the blame-the-British-press strategy plain as he complained of the “toxic” environment.

It may well prove to be a winning formula in America, where the rich and famous can control a media that largely worships at the altar of celebrity.

Yet while many will rightly feel sympathetic towards Harry for the mental anguish he has suffered, they are also likely to have more reliable memories than his new-found and famously fickle US audience.

They will remember, for instance, the miles of column inches that were written in praise of the 36-year-old’s two tours of Afghanistan and the hugely positive coverage of his charitable work including initiatives like the Invictus Games.

They also won’t have forgotten the warm welcome Meghan was given when she first arrived in Britain and how thousands lined the streets of Windsor to applaud the newlyweds’ carriage procession in May 2018.

They are also unlikely to lose sight of the fact that beyond all the PR puffery and benign blather with close friends masquerading as grand inquisitors, there are two sides to every story.

By only seeking favourable coverage, while their Royal relatives take the rough with the smooth, the Sussexes risk accusations of having ideas above their station, exemplified by the rather negative reaction to their recent suggestion that “service is universal”.

The timing will also have struck some as a little off, coinciding with the 94-year-old monarch making a historic intervention in the coronavirus vaccination drive, while her 99-year-old husband remains in King Edward VII hospital.

Part joker, part deep-thinker, and undoubtedly a sensitive soul, Harry has always been a complex character, which is what has endeared him to the public over the years.

He became one of the most popular members of the Royal family precisely because he used to take the work seriously but not himself.

While we were treated to a shimmer of that familiar sparkle on Thursday, the man on the Clapham omnibus could have been forgiven for sensing the slightest hint of regret.
