I recently helped out at an Orchestral job. My friend said he'd lend me a Trumpet (as my own is rubbish). On arriving I quickly found that I'd forgotten: a. A mouthpiece for said Trumpet. In my defense I was kind of expecting one to be there. Fortunately I had taken my Cornet with me (glasses, valve oil, etc) so used mt DW 3B with paper wrapped around it; b. A music stand (don't the drummers normally bring those too). Again, fortunately my friend had a spare; c. Best of all, I went to put on my bow-tie only to find I'd picked up by 9 year old son's - it was a few inches too small around the neck. Once again, fortunately, there was sticky tape available and my friend stuck it to my neck. I've seen fellow bandsmen forget music, uniform, mutes and even instruments - but not all at once. What kit failures have you experienced?
