I pinched the bulk of this from Brewer's Dictionary of Phrase & Fable - so it's not really my work. But I thought it was an interesting and fun way to express the term "never". The first two verse are mine.
We want to draw a line under the past,
absolve the criminals of their crimes,
but we wish to keep our celebrations,
our anniversaries of historic times.
We want to fly our flags and march our routes,
stiffen our backs and dig in our boots,
we want only what we want for ever and ever.
Compromise? Never, never, never......
....in the reign of Queen Dick,
not in a month of Sundays,
not in a million years,
not in donkey's years,
when Dover and Calais meet,
when hell freezes over,
when pigs fly,
when the world grows honest,
when two Fridays or three Sundays come together,
at the Greek calends,
at the latter Lammas.
