Yeah a couple of times...
Most famously I stuck a car in a ditch 2 days before a contest and had to play in a neck brace.....ultimate agony. Still, turning up with my bow-tie on over my brace made a few people laugh
The other one was having a tooth pulled on the Thursday before an area one year. I went to the practice, but could hardly play due to the extreme pain - felt like someone was sticking needles in my gums whenever I blew. At the end of the rehersal the inside of my mouthpiece was red :shock: Yuk! The best thing about it was everyone buying me brandys "to ease the pain" in the bar afterwards - I've been hooked on the stuff ever since
....the things we do for band....... :roll:
