In the fifties I remember mostly people dancing Rhythm numbers to the Lindy (Lindy Hop), there was still some older people doing the foxtrot, Peabody, and the Waltz. With rock hitting the scene dancing evolved to the slop, which for us was the first dance you didn't touch your partner no set pattern you did what you wanted on the dance floor. Later we had the mashed potato, the watusi, the stroll, the twist, the limbo, the fish. I'm sure there were more that I don't remember then there was the Disco dances. How many dances can you name that I missed?
