My New Year's Eve resolution is to find the origin of this expression:

        "Aha She Cried and Waved her wooden leg aloft."

It's an expression that lots of people (especially  mothers around 70-ish
now) use when they might have said "eureka" or "I found it."  I have looked
all over -- in Victorian Parlour Poems, in books of quotes, slang and
Canadianism (although I think it is probably British but I have no idea why I
think this). At one point it was thought to be from a parody  on Cassabianca
by Clara Denton  but it isn't.

Someone once suggested that the next line was   "...but the villian he still
pursued her. "    and another version:
                Aha she cried in accents wild
                and waved her wooden leg aloft.
                Tis false tis false and with her evil eye
                she swept the garden path.


Any ideas?  I will be ever so grateful.
