Walrus - name of the Russian march: Preobrazhenskij (a Russian Guard Regiment, if I remember right). This march is also in the Prussian collection of marches for the use of the Army.

Susanne - the ditty Herr Radetzky ... is not sung to the tune of Radetzky march, but another Austrian march whose name I have forgot (Hoch- und Deutschmeister, at the end?)
