Until now my favorite April Fool gag had been the BBC's film of gathering in the spaghetti harvest in Switzerland, first broadcast in 1957. In case you haven't seen it before, here it is. (You can see a 'making of' vignette here.)
It's now been joined at the top of the heap by this year's April Fool contribution from the King's College Choir in Cambridge. If you, like me, enjoy classical choral music, this is an absolute hoot!
Congratulations to all concerned.
