A 'church' for atheists? Yes, one is coming to Madison, with monthly services.  (Wisconsin State Journal, 8/3/2014)

How it got its start.   The first-ever Sunday Assembly was held about 18 months ago in London, launched by two British comedians, Sanderson Jones and Pippa Evans. In a guest column in the New York Times, the two said they started Sunday Assembly “because the idea of meeting once a month to sing songs, hear great speakers and celebrate the incredible gift of life seems like a fun, and useful, thing to do.” 

There is now a nonprofit corporation in New Jersey called Sunday Assembly in America, which is providing support to existing U.S. assemblies and helping launch new ones.
