Everyone else has pretty darn well said what I feel about this.

Just because he's your bio dad doesn't mean diddly squat. He walked out on you and your mother and has therefore given up all rights to you and any right to voice his opinion.

Since it is your day, YOU get to choose who you want to walk down the aisle with you. If that sorry excuse for a father has no positive feelings for this occassion, frankly he is welcome to NOT SHOW UP... no need for him to cause you any stress on YOUR DAY. It looks as though he's given you no reason to try to keep in touch with him.

How is your relationship with your stepfather? Heck, have your mom walk you down the aisle (like some suggested).
