First question, on which rhw abswers to all the other questions will hang. What is the tour for? For the perdormers to make a living? For the performewrs to get themselvesbetter known? Or for the performers to have a good time? These are not mutually exclusive( a good tour should do all three), but we do need to know what the main priority is. Basically, are the musicians professionals, or schoolteachers looking for a bit of fun during those famous long summer holidays? Because the these two categories need very different types of tour.
