Remember how everyone used to freak out over those clean-cut young Beatles and their haircuts? Well as the '60s moved closer to the '70s, those short haircuts grew out first into something more psychedelic and later into something, well, mullet-y.

For a majority of the '70s and into the '80s, Paul McCartney made the mullet his hair style of choice. During the '70s, it was mostly straight and long, as he let his "Beaver Paddle" flap in the wind, but as the '80s came about McCartney adopted his straightened locks to a more permed style.
