This is actually pretty cool. As much as I HATE wedding reception videos, this one works for me as it was not completely staged.
This bride and her husband were preparing to have their first dance to a Mark Wills song. Then the DJ's sound system appears to go kaput.
To her credit, she didn't go all Bridezilla, she kept her cool. As a keyboardist begins to play the song live, THEN the bride loses it as Mark Wills (pictured above) himself comes out to serenade.
LOVE her natural joy and reaction
