This just in from internationally known oboist Nicholas Daniel. TAKE NOTE!:
Musicians! I just managed to spark an alert at Heathrow and was delayed so much that I missed my flight because of something in the small humidifier in my oboe case. Hautbois Marigaux kindly put it there to help with dry conditions but on this occasion it caused a big problem. I advise you to put it into your liquids when you travel.
The strange thing is that I haven’t had it filled up for ages, I simply forgot, but I filled it last night from a jug we had been drinking water from in the interval…. It’s been taken away to be destroyed!
I was described afterwards as a ‘special’ and they took my passport details….
