Many Church of England incumbents (most famously, the late Very Rev’d Colin Slee, Dean of Southwark) have banned the singing of Blake’s Jerusalem in their churches. The ostensible reason is that it is not based on a firm religious foundation. Some people have tried to rehabilitate the tune by setting different words to it.
But that bastion of Little England Toryism, the Daily Mail, quotes a gay Tory MP as saying that if this continues, the only ceremonies at which Jerusalem will be sung are lesbian and gay same-sex civil partnerships.
That doesn’t bother me at all.
