They have a way of doing that. When I said "you", I was addressing "GUESTcoxcomputing" (etc), and should have made that clear; your (Lighter's) revival of this thread is worthwhile and interesting.

There ought to be other people who remember the "socks" parody, but they may not make the Armentiers connection, perhaps. This was the mid 1960s, I think, and it would certainly be older than that. I should add that the "King of Rome is dead and gone" lines were generally sung very slowly, and in the minor key, returning to the major and a brisk pace for the final line.
