I have attempted to set out for you, the basics of the traditional Wedding speeches.
These rules are not hard and fast and nowadays other people like to speak such as the Bride, the Chief Bridesmaid and the Father of the Groom. It is preferable to prearrange who is going to speak and the order, especially if there is a Toastmaster.
The Best man’s speech should be funny, but it should not be an extension of the Stag night and it will be better received by the family audience, if it is written accordingly.
It has also become more common to shorten the ordeal for the speakers, by holding the speeches before the meal. Personally, I think an audience who have had a nice meal and possibly a few drinks may be a more receptive audience.
