U.S. - A new printing of the Unitarian Universalist hymnal just contains one song: John Lennon's "Imagine."

The official UUA hymnal, titled Songs of Doubt, includes the popular song in a few dozen different arrangements and nothing else.

Now UUA church members can sing along with deeply spiritual lyrics such as "Imagine there's no heaven / It's easy if you try / No hell below us / Above us only sky." While UUA churchgoers aren't required to participate in hymn singing, the preaching of the Word, church attendance, or anything else, church leaders hope this move will encourage more parishioners to sing along.

"The old hymns were problematic because they mentioned Jesus, the cross, and God sometimes," said a UUA pastor of doubt formation. "Now we can sing that there aren't any countries, nothing to kill or die for, and no religion too, just like the Great Feminine Spirit in the sky would have us do."

"One day all the world will live as one, as Lennon's classic hymn says," she added. "Preferably under communism."
