I'm surprised this little ditty has not been included on here, sung in Cornwall in the 1970s:

We break up! We break up!
We don't care if the school blows up.
No more English, no more French
No more sitting on the old school bench.
Teacher! Teacher! We don't care,
If we see your underwear;
Is it black or is it white;
Oh my gar its dynamite!

Not sure where it is from - French was certainly NOT a subject at our primary school. I suspect older siblings at Redruth grammar school.
