A line that puzzled me as reported in a few of the above posts:

And off to lieber August, September, October
    and
Ve are off to lieber August, September, October
    and
Octelebra August, September, October
    and
We were off to leiber august september october
    and maybe another variant or so.

I'm firmly of the opinion that the beginning of that line
was originally "Ach, du lieber August" (Or "Augustine"),
which was folk processed by folks who didn't understand German
or the well-known song that starts that way, which garbled the
German words, and maybe somebody thereafter garbled THOSE
folk-processed words, and so forth.
