I note that Andersen's 1939 performance includes the "Schon rief der Posten" stanza, but in 1968 she has dropped it.

The bawdy stanzas recalled by GUEST and Wolfgang have a counterpart in the Spiegel article (attributed to "ein unbekannter GI"):

Down by the Bahnhoff,
American soldat
Zie haben cigaretten
and a beaucoup chocolat.
Das is prima, das ist gut
A zwanzig Mark for fumph minute.
Vie fiehl, Lili Marleen?
