I decided on a great song that I really want to use as I walk down the aisle, it is just the last bit of the song, just the instrumental part. Its a song that means a lot to my FI and I, but as I was talking to him about first dance songs, he mentioned that he thought this same song would be perfect for our first dance. Would that be really weird to use the end instrumental part as my processional song and then use the whole song as our first dance song?
