My mom and I both tried to surprise each other with the same song. I told the music team I wanted Black Bird because my mom used to sing it to me when I was an infant to help me sleep.
She apparently found out who the music team was, I think I said who we were using, anyways, she called them up and said she wanted to surprise me with a song. So they called my number and said "Uhhhh, so is your fiance there? We need to uhhh, talk to her directly."
I had no idea what was going on. So I handed the phone to her and she said, "ok you've got to leave the room." Now I'm definitely in what the fuck mode. turns out, the DJ wanted to know if someone was trying to prank him and figure out what was going on. I don't remember how my wife talked me out of w t f mode. Anyways.
So the song plays at the wedding for our dance and we both think we've surprised each other. And once we both realized what had happened it was a really, really great moment.
