If it's in the context of a documentary (which it is) as opposed to
"There will now be a party political broadcast by a dead politician" then I guess it's ok, although why we need fetishise and commemorate this impressive but hideously misplaced and inappropiate piece of oratory, even if it is a 50 years anniversary, I am not sure.
No it shouldn't be banned, it was an important part of our history which has inspired people in almost equal measure to love and loathe it's contents ever since. As long as it's presented in it's historical context and no-one allows the BNP, EDL, Britain First mob to hijack it as propaganda I think it's a very interesting thing to hear.
I'd like to hear it again. Radio 4's PM programme has had an excellent feature ove rthe last week o so where they broadcast famous speeches including Martin Luther King, Robert Kennedy, Robin Cook and Ronald Reagan- and all have been spellbinding (I hadn't realised back inthe day how good Reagan was at this sort of speech). It would be fascinating to hear EP's full speech again in the context of what we know now and what we feel now about what is acceptable and PC to say in public
The notoriety stemmed from his use of a quote from Vergil's Aeneid. Aeneas had gone to consult the Sybil as to what she foresaw for the future. Her reply was:

Et Thybrim multo spumantem sanguine cerno"
"...wars, terrible wars
And I seem to see
the Tiber foaming with much blood".
