Here's a thought.....we had each couple in our bridal party walk in to seperate songs. Like, the DJ introduced them, and then as they were walking in, we played a small portion of a song that was fitting to one or both members of the couple. Like, for instance, Adam's dad was his best man, and EVERYONE that knows him or my husband knows he likes to build things. So he and my maid of honor (because she totally didn't have an opinion on it and was cool about "going with the flow") walked in to the "Home Improvement" theme song. It was mostly all for fun, and it made everyone smile.
My brother walked (or rather, "strutted") in to a song from "Cowboy Bebop".....needless to say the bridesmaid that walked with him was thoroughly embarassed. :)
