At the traditional weddings I have been to:
the bride's father has walked her down the aisle (in this country at least)
the bride's father has made a speech at the wedding support
the bride's father has danced with the bride
(some of them have danced a good deal better than the groom)
At my wedding there were also people singing and people playing musical instruments that I am unable to play. Plenty of reminders that I am not the only person in the world.
To be fair, my MIL does upstage me on pretty well all occasions. That is because she is great fun, a great character and a truly lovely person. I can live with that.
