Page 346 "Shanzenbach suddenly began to sing 'The Marseillaise.'"

From page 346 of the book:  Shanzenbach suddenly began to sing "The Marseillaise," the French national anthem, with Owen providing accompaniment.
    "How I love that song," cried Revenant. "Tell the Good Walter about 'The Marseillaise.'"
    "I don't want to give a history lesson," said Ebert. "I'm half drunk."
    "You know, Walter," began Revenant, "it was composed in 1792, at the beginning of the Revolutionary Wars. That little man, Napoleon, he didn't like it. Screw him."
