My sister's, husband's sister's husband (Did that make sense lol) Is walking me down the Aisle. I've known him since I was 6 and we are pretty close. He doesn't have any kids and when I asked him he was all smiles. You would have thought I told him he won the lottery! So I promised him a dance to go with that walk

Thing is I don't really know a song to dance to with him.. I don't think I want to use The way you look tonight. Seems like something your BF, FI, or someone would typically say.. Any suggestions on what we could do?
