Some of us, myself included, may struggle for months to make sense of what happened to us over a 46-song, three-and-a-half-hour musical travelogue which still seemed to be over too quickly.
I am a man in my 50s. In front of me stood an 11-year-old girl in a sparkly jacket who spent much of the show swapping friendship bracelets with children even younger than her.
What was I doing here? And if primary school kids were loving it, why was I, a fellow who likes to consider his musical tastes refined, loving it too?
