According to John Cleese, the troupe went to tour the Dachau concentration camp after filming, one day. When they arrived, however, they were told that the camp was closed for the evening, so they wouldn't be allowed in. Graham Chapman suggested, "Tell them we're Jewish."
The English subtitles for the "Lumberjack Song" show the same lyrics as the English version ("I wish I'd been a girlie, just like my dear papa/mama" [both were used]). However, it doesn't take a German to notice that Michael is clearly singing "Uncle Walter" at the end of the line (so as to rhyme with the German word for "bra", namely "Bustenhalter").
In addition to recreating classic sketches ("The Lumberjack Song" for one), several new sketches were written specifically for this show, such as "Little Red Riding Hood", "William Tell" and a herd of cows doing "Merchant of Venice".
The first special (which the Pythons performed in German) has also been called "Monty Python in Deutschland". The second special (which they performed in English) was referred to in contemporary guides, at the time of its original British airing, with the subtitle "Schnapps with Everything".
