Dancing with Brother

Ok, so my brother was saying the other day that he would be honored to walk me down the aisle. He's 5 years older then me, but my whole life I always matured faster then him, so I really look at him as my younger brother rather then my older brother ... at least most of the time. Lol. I really only want to have my Mom walk me down since my Father can't.. So, I was thinking of surprising him with a brother sister song at the reception. Any one have any suggestions on what song to use...? Please lemme know. Thanks mcuh! :)
