There IS a late-season strain of Influenza B going around. If anyone in their band has that, I'm not surprised they cancelled. Several million people worldwide died in the 60's from a similar strain, and until recently I never understood how. I caught it last month. I was VERY sick, with a fever so high I was hallucinating (and not in a good way, either), serious body/joint pain, headache, stiff neck, cough and ZERO energy for almost three weeks. There's no ??magic? treatment, only fluids and aspirin to control the fever. A quick swab test (10 min. wait-time) can diagnose presence of the virus, and the "strain." I feel sorry for anyone who gets it. My only advice to them is: Surrender and get into bed. Sleep and stay warm. You'll be rockin' again soon.
