What is a good song for the bride and groom to enter the reception as husband and wife?

My daughter is getting married this Saturday, and we need a cool, upbeat song for her and her hubby to enter the reception right after they are announced as husband and wife for the first time. I know YA would give us some great ideas.

My friends used 'Beautiful Day' by U2, it was great.

Im getting married in June and my fiancee and i are coming out to "Eye of the Tiger" from the Rocky movies. We love those movies and it means something to us, plus the beginning is upbeat! we are excited! have them pick something out that means something to both of them, maybe a favorite movie song like mine, or a upbeat song her and her fiancee like

'Bubbly' by Colbie Calliat.

'Saltwater Room' by Owl City

Pink- Get This Party Started

Gretchen Wilson- Here For The Party

(I'm sure both songs are probably on youtube if you haven't heard them before.)

Everything ~ Michael Buble

If their up to something more classic jazz i would say "It had to be You" by Frank Sinatra

I would pick something that is special to them ... not just something random from suggestions.
