With the exception of the comedy rock band, “The Upper Crust,” once powdered wigs went out of fashion at the end of the 18th century, men kept their hair cut short and neat until the early 1960s. When the Beatles appeared on the Ed Sullivan Show in 1964 with their mop-tops it sparked a revolution in men’s fashion and the youth of America began to forsake their crew cuts in favor of long hair. The mop-top was so named because it reminded the older generation of a wet mop.
