Sorry to nearly hijack your thread Moggy , it wasn’t intentional .
A quick Google reveals that many Battle Of Britain Sunday services are being held next weekend , 21 September including the Westminster Abbey service , some details here although too late to apply for a ticket ; http://counties.britishlegion.org.uk/media/3924130/Log-176-14-Letter-from-RAF-Ceremonial-Office.pdf
There was a good turnout for the Thornaby service including many children from the local schools , one of which was Bader Primary School . I think Thornaby holds its service on a different day to Stockton , the main borough town , so that civic digniteries can attend both services ?
