Whilst I am not religious and don't own a faith, there is something in tradition hymns which can really strike a chord with the human psyche. Having been brought up with many hymns (both mainstream and Brethren), these have stuck with me over the years.
One particularly resonant example is "Abide With Me" - sung, of course, on the (former) terraces of Anfield and, today, in many Remembrance Day services up and down the country.
Here is Emeli Sandé with a recording of the version she sung so electrically at the Olympic Opening Ceremony. Take a couple of minutes to pause and contemplate on the song and on the meaning of this day.
