Wedding Song Ideas?

I'm looking for a large ensemble song that would work to sing at my wedding reception coming up in April. I have many guests attending who I've sang with in various shows and singing groups over the years and would love to find a song we could all sing together at the reception with simple but impressive harmonies. I'd like to have something that showcases multiple soloists.

So far I've thought of the All Shook Up arrangement of Can't Help Falling in Love - but does anyone out there have some other ideas of Broadway group numbers that could work for something like this? My fiance isn't an Elvis fan but I love the style of this arrangement. Appreciate any suggestions!!
