Well, German women and alcohol are the subject of the Deutschlandlied's second stanza after all. Which is not sung anymore, but presumably only because after ditching "Deutschland, Deutschland über alles" it would be somewhat awkward to start the national anthem with "German women, German faithfulness, German wine and German song".
The Zapfenstreich is not so rare BTW, about any three-star general and civilian equivalent gets one upon retirement, including allied commanders; I've been to one for an outgoing USAFE chief. What is rare are the ones in public squares; the vast majority is literally hidden in the yard of the MoD's Berlin seat at the Bendlerblock, and only the ones for ministers and chancellors are usually televised. At the 2011 Berlin I&I some of us tried to watch one for I believe the outgoing German commander of the NATO Defense College from outside the fence, but could see very little because the adjacent streets were blocked off for security reasons.
And yes, with the return of the Fritz helmet shape, there is an even more distinct, uh, historic feel to the event. Personally, I have long decided that if I should ever qualify, I will have the Star Wars Imperial March played as one of the three tunes the recipient gets to select.
