Atleast two of my cousins danced with their SOs on their weddings in Pakistan.
My SO is too serious and Ive also become pretty serious to give it a try.
Bride & groom dancing on the wedding party? Hmmm.... I dunno man
if this is going to be in PK, i would say "WHAT!?!? cuz seriously I have never heard of that"
Re: Wedding Dance - Slow Song Selection
Nothing's Gonna Change My Love For You by Glen Medeiros and Bailamos by Enrique Iglesias would also be lovely choices.
I went to one where they did something like this. The couple were very good at dancing to begin with and it was hilarious. Everyone had such a good time.
