I will survive
Gloria gaynor
Not an ideal wedding song.. but i agree, it will fill the floor at a wedding, 21st and even a funeral.....
Another is Band of Gold, which again is about someone leaving, but it get them out their seats and on the floor.
Just wanna dance the night away, were seneritas doodoaadeedaaaa,,,, hate that song, but again they are all up dancing to it.....
