Well not quite given the demonstration on Le Petit Journal which showed just how impossible it would have been for that many people to have stood still in such cramped conditions let alone wave flags and applaud as could be seen on television footage of the event.
Oh well, what's the odd 100,000 plus between friends.
It was possibly only a slight exaggeration and an event, after all.
Something, which along with hyperbole, seems to have become a trademark of the 2012 French presidential election campaign.
And that's the most important thing isn't it?
