can't believe this hasn't been recommended before. if you haven't heard it, you should probably be ashamed of yourself.
one of the best party songs ever recorded,
it practically commands you to get your ass in gear and have fun. i really don't know what more to say about it, check it out, it's just incredibly solid.
you can find it on volume one of the always reliable 100% dynamite compilations from studio one.
available on CD - 100%dynamite (studio one soul jazz records)
