My son is learning the trumpet, and has now been told to ‘have a drink after you finish practising’. Of course water is what is meant, but it explains a lot!
In fairness to brass players everywhere, I will recount what happened at an orchestral concert which I sang in a few years ago (but within the lifetime of this blog). After the interval the conductor came on stage, raised their baton, looked round the orchestra and found that there was an entire section missing. Turned out both flute players were still in the pub and they had to be hastily extracted before the performance could begin.
