Remember how everyone was saying that LADY GAGA'S "Born This Way" copied MADONNA'S "Express Yourself"?
--Lady Gaga claimed Madonna was cool with "Born This Way", but Madonna later called it a "re-do" of "Express Yourself" . . . and added that she thought the similarity between the two songs was "interesting."
--Well, Madonna seemed to take another shot at Lady Gaga in Israel, when she went into "Born This Way" while performing "Express Yourself". And yeah, the two songs fit together like a glove.
(--There's amateur video of this on YouTube. The quality isn't the best, but you get the idea. She transitions into "Born This Way" at about the 1:00 mark.)
