 and had a spoken introduction in an exaggeratedly English accent "Madames et Messieurs, pardonnez-moi mais j'ai oublié tous le français que j'ai appris à l'école" Although the title is "The flies crawled up the window" my memory is that their activities are described in the present tense as befits the first verse.I’ve got a little problem it really is sublime
It’s where do all the flies go when it is winter time?You ought to know the answer 
But I’ll tell you once more
As Mr Gladstone told the Queen in 1864
The flies crawl up the window
It’s all they have to do
They go up by the thousand
And come down two by two
The flies crawl up the window
They say we love to roam
So once more up the window
And then we’ll all go home
The flies crawl up the window
And this is why they do
If they don’t crawl up windows
How are they to see through?
