If you just want to get together, sing a few songs together with family and friends, and bond with human beings, then this is for you. It's all the community, without the superstition! This was started by by people in London but it's now been done in other cities, and they're bringing it to San Diego. It's not yet scheduled but the target is October or November. If you go to this link you can reserve a spot and show the Assembly that it's worth coming to San Diego!
This will also be a media-worthy event, and the San Diego community is still growing and the media exposure would be excellent.
