A Guid Nychburris Special is planned for June 17-19 with Russell Kane and Rosie Jones and a family event.
There’s a packed programme for the final weekend, with Rich Hall, Colonel Mustard and the Dijon 5 and Stanley Odd alongside the headliners.
Tickets for all events go on sale on Wednesday morning.
