Qué canción era número uno en Francia el día en que naciste?

Alguien escribió:

once upon a time there was a tavern
where we used to raise a glass or two
remember how we laughed away the hours
and think of all the great things we would do
those were the days my friend
we thought they'd never end
we'd sing and dance forever and a day
we'd live the life we choose
we'd fight and never lose
for we were young and sure to have our way.
la la la la...
