Processional and Recessional Songs?

On the wedding program, do you typically include the bridal party processional song, bridal processional song, and recessional song??
What songs are you guys using for these things?
My band recommends Spring from Four Seasons and Pocabell's Canon (sp??), but I haven't heard them yet...

The programs I've seen always include the processional and recessional songs. Spring from Four Seasons and Canon in D are both beautiful.
