Closer - Nine Inch Nails (NIN)
This is an extreme example of a song that's too graphic and intimate for a wedding celebration. It's just not appropriate for a family gathering. So, unless you're having a late night wedding aimed exclusively at savvy adults, go for something less raw and evocative. If the lyrics of your special song are too raunchy to print out on your invitations, consider toning it down with another choice.
