Well, was playing with one of my bigbands last night up at Callander Jazz Festival, & to be honest I'm completely bummed out. I went in early, had a nice, normal gentle 5 minute warm-up which was fine, went for a quick sandwich. Gig started about half an hour later result: no chops, no sound, no response, no range. Just rubbish all the way. Lips were extremely swollen, it felt like my mouthpiece was coated in vaseline! No grip, no feeling. In the end up I had to switch to a 3C in order to get any kind of sound out, & even then I had to use far too much pressure to get the job done. The only thing I can think of is that something I ate in the sandwich (tuna, sweetcorn on brown bread, with some fresh orange juice, salt & vinegar crisps) caused my lips to swell & become completely unresponsive. Never had anything like this before, so I'm completely confused! Got another gig tonight with another bigband, so I'll just need to withold judgement until tonight. This morning, my lips feel like they've had the battering of a lifetime! To say I'm confused & anxious is a slight understatement.
