I've seen those photos several times but never te videos before, I like this one a lot:http://www.britishpathe.com/record.php?id=74861
(1960 :- there's a scene of the 'seahorse' lamps at the Henry Grattan statue on Dame St in there (I know there was a discussion either here or on boards.ie about when they were moved)
They've put this video back up with sound. Click the image to view.
