This is a video still of the Queen's Diamond Jubilee Thanksgiving service at St. Paul's Cathedral in the City of London on June 5, 2012. The gentlemen pictured are the leaders of the other faiths (i.e. not Church of England) invited to the service.
At this moment, the congregation was singing the hymn below. Members of all the different faiths seemed to be joining-in in the singing, apart from the man on the right, the Chief Rabbi of the Britain, Jonathan Sacks, who appears to be looking at the words of this Christian hymn with utter contempt. Viewable at 34:00 on this video.
