They have released another track this Christmas that can be downloaded for free. It's called No Her, No HYmN.
While it can be downloaded for free, if you go to their website, they suggest making a donation to Scottish Care & Information On Miscarriage, an organisation that "...offers counselling for women who have suffered miscarriage, stillbirth or neonatal death following loss, before trying again and in pregnancy following loss. Our counsellors are university trained and have personal experience of loss."
Despite the liberal application of jingle bells throughout, this is not your typical Christmas song and I'm not sure it will find its way onto my Christmas playlist but it's worth a listen and it's a worthy cause.
