If anyone isn't aware of it, tomorrow is Mystery Worshipper Sunday here in London. The website
Ship of Fools is running this event.
Mystery Worshipping has been going on for a while, and is the ecclesiastical equivalent of the Mystery Shopper. We worshippers go to a church where we are unknown and rate the service we attend. It's been lots of fun for me.

I have been doing this for quite a while, and have rated such places as
St. James Cathedral in Chicago,
St. Michael's Episcopal in Marblehead (my home town), and
St. Peter's Lutheran in Manhattan, as well as
All Saints Margaret Street,
St. James Garlickhythe and
Southwark Cathedral here in London.
I can't yet say which church I'll be visiting tomorrow (need to keep it a secret in case they're looking around the 'net) but I will say that it's not Anglican (bummer!).
I will post the URL of the report on 10th May, when the reports of all 60 London Mystery Worshippers are posted on the website.
