Should Jerusalem be sung here?

The Church of England has issued new advice to churches on the use of the popular hymn Jerusalem at weddings. In the past, some conservative groups have claimed that it's not suitable for official services. William Blake, who wrote the poem later set to music by Sir Hubert Parry, had a distinctly unorthodox take on Christianity. Reverend Peter Moger, "worship development officer" for the Church of England, compiled the guidance, which explores some of the contentious issues. On the question of whether or not it's appropriate for weddings, he acknowledges that "opinion on the matter is strongly divided". You might say it doesn't matter whether the theology's right, so long as people know the tune and enjoy singing it. But then no one would expect churches to allow the bride to walk down the aisle to the strains of The Number of the Beast . What do you think? A storm in a vicar's teacup, or something more serious? Would you want Jerusalem played at your wedding?
