To the tune of Glory Glory Halleluja (From U. Chicago Beer party ~1955). Contributed by Moe Hirsch. (Verse 3 added by Mark Wilson; verse 4 added by Joel Robbin.) Analysts, topologists, geometers agree: When it comes to generality, there's none like Bourbaki! One theorem by them will equal N by you and me, Bourbaki goes marching on! Chorus: Glory, glory halleluja, Their generality will fool ya-- They're axiomatically peculiah! Bourbaki goes marching on! To prove that two plus two is four, here is what they do: They show that A plus B is C if A and B are 2; We know that C is half of D and D is four times 2, Bourbaki goes marching on! [Chorus] They commenced to write a book to train young analysts, but in filling in foundations, they encountered many twists. Now their dream to end in finite time has vanished in the mists, Bourbaki goes marching on! [Chorus] In the glory of the twenties came to be homology: those groups of Emmy Noether which transfigured you and me. As she tried to make them cyclic, Bourbaki has made them free! Borbaki goes marching on! [Chorus] \end{document}
