I just listened to it, with headphones and put the volume up in full heh... it is very beautiful piano version of my heart will go on. Perhaps someday I'll try to play it for fun if I find any piano nearby... I used to have piano, as I was listening and watching that video, I just realized I missed playing the piano.
Anyway Angel and RR, don't let anyone to control your wedding for songs, dresses, flip flops etc, since it is your wedding, everyone (family, friends etc) should respect your wishes.
