16th July - Miranda stars her summer music tour. It is ongoing and completely wipes out the schedule for any filming to happen from The 16th of July all the way to the middle of September. There will be at least 3, and possibly 4 or 5 episodes still to film before she leaves, that will have to be filmed after she comes back.
