Official 25^th anniversary celebrations were held on 25 June, but the fun and games happened on CERN’s real birthday, 29 September. As well as sports, sideshows, films, and Genevan Pipes and Drums, there was Happy Birthday, CERN, written and recorded for the occasion at Fermilab.

Verse three goes like this:

“Here's the toast we're proposing:    
may your future be greater,  
  And the budget imposing for your  
  next accelerator;    
May your staff be effective and   
your beams full of pep, 
  May you gain your objective of  
  constructing the LEP!”
