Your father sounds like he's got a great sense of humor. Ultimately it's your day. That being said, you're already going to be the center of attention. This might be something really fun and really memorable. If your set on not doing something this quirky, find a compromise. Maybe your Dad just wants to be the center of attention at some point. Maybe him and someone else can choreograph another song. Or maybe something not quite this elaborate.

Whatever you decide remember to have fun on your day and smile. It's so sad when a bride looks like a deer in headlights for the whole event.

I dreamed of a wedding of elaborate elegance,
A church filled with family and friends.
I asked him what kind of a wedding he wished for,
He said one that would make me his wife.
