it's no secret that Beyonce' never does anything original...clothes, music, dancing...nothing.
here is the original "single ladies dance" inspiration..the legendary Bob Fosse' (google him if you don't know)
it's amazing how these ladies work that thang...this was made in the 60's set to "walk it out" for your viewing amazement.
Im posting the original and the version set to different music, both are AWESOME!!!!!!!!!
