I don't have a link to a video, but my wife and I were on a flight from Birmingham to Murcia several years ago when we witnessed the sort of cabin-based announcement you refer to.
From memory, his announcement included wishing a young passenger happy birthday and how he (Pablo) would have loved to have been able to fly at a young age. He also said it was a shame the boy wouldn't be able to visit the flight deck during the flight because of the rules.
As we taxied out he drew our attention to some plane spotters and remarked that was what he used to do as a boy.
I seem to recall that he was standing in the cockpit door wishing everyone a good holiday as we disembarked in Murcia.
In any other business such a personable approach would most-likely be commended as generating customer satisfaction and loyalty.
I cannot comment on any technical aspects of the flight, except to say it was completely uneventful.
