Ive never heard anyone speak but possibly the first wedding I ever went to was a wedding between two of my School friends. They were very young, both being 18 at the time. The wedding took place in a beautiful old church in Formby near Liverpool (England). All was going well until the "Speak now or forever hold your peace" moment. There was a slight pause as always when everybody wonders if somebody is going to say something, and as often, a few nervous giggles (especially with a room full of 18 year olds !), and then there was the most almighty crash as the organ pipes from the 80 year old Church organ fell off the wall !
Fortunately Karen, the Bride, saw the funny side and quick as a flash said "anyone else ?".
This might have been seen as a bad omen but I am happy to report that the couple are still together and that incident took place in 1980
