No unregistered bands are not allowed to compete at easingwold hence why the tmp band was allowed to play but not compete.
Ripon takes place in May usually and is for 3rd/4th section and unregistered. The organiser is Peter Gilby secretary of Ripon City Band. Don't have any further contact details for him
Middleton in Teesdale takes place in July and is for 4th section, youth and unregistered bands. I don't have any contact details for this one
