Fran, I empathize with your situation. It is very difficult being the pivot man in the group. For years I've told my guys to have SOMETHING ready just for emergencies. Whether it be a CD, a laptop or a loaded arranger the members who rely on my cache of music need an escape route if I'm not there. I'm sure the guitarist and sax man could make a go of it, but not without rhythms and such. Your guys should have been prepared.
