Here's another idea, kinda spun off from the original.
(It's entirely possible that this sort of thing already exists somewhere on the 'cat, and I'm in blissful ignorance of it)
Rather than organizing a fixed string of concerts, we might at the least maintain regional/city lists of players, willing hosts, people plugged into the local venues, free publicity, etc...
Then whenever a 'Catter is traveling and needs a between-shows gig, or wants to individually organize a "Mudcat Touring Roadshow" the resources are already assembled.
I hereby volunteer for the host and free publicity lists from Dallas.
All the Best, Jeff
