I love St Paul's Cathedral. It's certainly my favourite building in London and probably the world. The outside is so majestic, the inside so awe-inspiring and seeing its shape on the London skyline always lifts my spirits and makes me happy to back in town.

There's a personal connection too. I was christened there in 1970 and then I carried Dad's banner there 3 times at the Michael and George service over the years. The final time was of course on Thursday and it was certainly a memorable occasion. The service was full of the sort of ceremony and pageantry that seems pointless and anachronistic right up until the moment when it actually starts when it turns out to be absolutely fantastic.

On Thursday we had the band of the Coldstream Guards playing music as the crowd gathered. We had the trumpeters from the Scots Guard playing a memorable fanfare for the arrival of the Duke of Kent and then again before and during the national anthem. We had the choir and the organ. Music is really where St Paul's transcends anywhere else I have been. The acoustics are extraordinary and somehow the space truly amplifies music: making it both louder, warmer, richer and more profound. But the real magic happens when the music stops. In that second or seconds that follow it's like the music is both there AND absent. The echo or sustain or whatever it is lingers and gently departs. To me it's truly sublime.
