Princes Charles, William and Harry have given a TV interview at Highgrove to mark the 30th birthday of the Prince of Wales’s Prince’s Trust.

We might have expected a high-profile interviewer. After all, the Prince gave a one-hour tour of his thoughts to ITN’s Trevor McDonald only a few days ago. But Jeremy Paxman it was not.

Who then? Ant and Dec, a couple of children’s presenters, recently promoted to the giddy heights of reality TV. So what did we get out of it?

Princes William and Harry reveal that they adore “trash TV”. Examples: Friends and Pop Idol. They also fight with their father over the television remote control.

William claimed to be a star in the kitchen. “I’ve done a bit at university when I had to feed my flatmates, which was quite hard work because a couple of them ate quite a lot,’ he said.

On their musical tastes, not surprisingly there’s a big generation gap. Just as the two boys look set to praise rap, their father interjects: “I tell you who I also think is wonderful is a chap called Leonard Cohen … do you know him? … he’s remarkable. I mean, the orchestration is fantastic and the words, the lyrics and everything, he’s a remarkable man, and has this incredibly sort of laid back gravelly voice, it’s terrific stuff.”

William points at his brother and comments: “Actually I’d say his taste was pretty shocking, but mine was very good.”

The interview was was filmed two weeks ago while William and Harry, both Army officers, were on leave from Sandhurst.

If you’re in the UK, you can watch “The Prince’s Trust 30th Birthday — Live” on ITV at 6.55pm tomorrow. An extended version of the Princes’ interview will also be shown on Sunday at 12.45pm.
