The last note went on far longer than it should have and nobody clapped until it had properly gone.

The trumpet came in like a memory of somewhere I have not been yet, and I found myself longing for a world that does not exist. Not yet.

I had arrived at the concert as a chaperone to my teenage daughter. But during the concert - which was spectacular in all senses of the word, I noticed such an amazing connection between the band and the audience, including my daughter, that I left firmly as a fan. The collective experience was amazing, but ultimately it was the power of the music - the energy, the lyrics, the showmanship that made tens of thousands of people connect and feel better than they had at the beginning of the concert.
