In the '70s and '80s, Martha Wash was known for singing club hits alongside the legendary Sylvester. With Izora Rhodes, she formed the duo Two Tons o' Fun, which was renamed the Weather Girls when their indelible 1982 hit "It's Raining Men" took off. Her titanic soprano voice is unmistakable, but it didn't stop multiple producers from employing much thinner model types to lip synch Wash's vocals in videos without properly crediting Wash. And all because Wash is overweight and not your average girl in the video. These videos included Black Box's "Everybody Everybody" and "Strike It Up," as well as C+C Music Factory's global smash that helped define early '90s dance pop, "Gonna Make You Sweat (Everybody Dance Now)."
