OK...This is more than a bit off topic but its driving me mad!!

They used to use it on french movies in the 60s (i think)

And the lyrics go

"Sha la la la la
la la la la la
na na na
Sha la la la la
la la la la la
na na na
Sha la la la la
la la la la la
na na na na
na na na naaaaaaaaaa"

Ok ....this is a long shot,but if anyone can help,I may just get some sleep tonight
