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.
