Yes. Definitely Granada rather than ITN, and regional - think this was catalogued as 'Late Scene Extra' in the archive ('Scene' was usually spun off into late night editions - that oft-repeated chat between Ken Dodd and The Beatles was recorded just a few days later)

I think there was a story somewhere that ITN weren't prepared to allow Granada to break news of the shooting first until they had verified it themselves (Granada's source was a phone call from CBS in New York)

Also worth noting the hastily-arranged epilogue - very unusual practice from Granada at the time, who usually left such things alone to ABC at the weekends.

Kaleidoscope's podcast does feature (in audio only) ITN's late news summary, preceding a Rediffusion epilogue and closedown - which somewhat surprisingly, diverges into other news, including a report on that night's TV awards that ensured most of the industry had been caught on the hop.

About the epilogue, you are quite right, Granada avoided religion if at all possible. Usually in the pre-1972 restricted TV hours era, Granada tended to start their proper schedule at 5.00pm or 4.50pm and run right through until midnight - and a fairly curt "Good Night" was the end phrase for the last bit in their schedule at midnight, whereas other regions had an epilogue around 11.30pm/11.45pm

Granada often used adult educational shows as a replacement for any epilogue. I remember one programme was "Music for Guitars" which replaced any epilogue.
