WATCH: Judi Dench Serenaded By Firefighters At Premiere

Of the many appropriate responses to suddenly finding yourself in the presence of Dame Judi Dench, bursting out into song has to be close to the top of the list.

So kudos to these members of the Fire Brigades Union, who after knocking back some pints following a protest, stumbled upon the recent London premiere of the new film Philomena and formed and impromptu chorus of praise.

In news that will shock no one, Judi handles the situation like a true Dame.
