Here is a link to a guardian article discussing secular carol services printed a few days after our own.
Led by John D’arcy we sang lots of songs celebrating christmas that did not mention Religion. This may sound contradictory and indeed on sending out the invites one person declined saying you can’t have Christmas without Jesus. We put this to the test, I did not do any fancy introductions it was not important to me who believed what but that we all wanted to sing together and that we recognised enough of the songs to make this possible.
We sang for a few hours and got plenty of strange looks from those passing the gallery but it really put me in the christmas spirit – for me this means spending time with family and friends, eating too much and relaxing.
