13. Regardless of the weather, an umbrella and/or raincoat. I learned the hard way. I set off in minimal light clothing on a hot summer's day to play at an event in a marquee in the grounds of a stately home. During the gig, thunder, lightning and torrential rain developed. At the end, I was soaked through to the skin as I made my way back to the Car Park.
I added recently some small pieces of wood to my own range. These are for placing under the feet of chairs. Why on earth will they be needed? Well, I’ve had enough of being asked to play for a couple of hours outdoors on sloping or unstable grass surfaces. This frequently happens at village fêtes and garden parties. Also they could be useful for holding doors open while colleagues unload drum kits, etc.
Other musicians have told me they take the obvious (spare reeds, spare cables and leads), but also: tiny flashlights with battery, thimbles, a multi-tool, cigarette papers to soak up condensation inside clarinet holes, insulating tape, cable ties, and biscuits. Reader Sam sent me this picture of the smaller of the gig bags that he uses. He also has a larger bag containing more tools, cleaning materials, cables, leads, etc.
