I am looking for a song to dedicate to my husband at our wedding something that says he is great in everyway and everything he does

A song for your wedding should reflect something significant to you and him. A song that signifies a special moment, event, saying, etc.

My wife and I chose Aerosmith's "I wouldn't change a thing:"

My suggestion: At Last, by Etta James. It's a classic.
