Creating clauses like these is an example of why laywers are Hell-bound:

Termination of the grant may be effected at any time during a period of five years beginning at the end of fifty-six years from the date copyright was originally secured, or beginning on January 1, 1978, whichever is later.

It just seems to me that we could at least make some effort to have simpler rules. Oh well. Gotta make the lettuce to support her shoe fetish somehow. (Song lyrics. I am not going delirious.)
