"Good King Sauerkraut went out, on his feets uneven..." I think there was only one more line (or maybe three); Kelly never did finish it. And the words to "Boston Charlie" can be found here.

I'm disappointed no one picked up on my Servitur cum sinapio.


2nd stanza:

The boar's head, I understand,
Is chief service in this land.
Wheresoever it may be found
  Servitur cum sinapio.

Translation: "It is served with mustard." Which seemed appropriate to talk about bratwurst and sauerkraut.
