Kids today, they don't appreciate how bad the mid-70's really were. They think Raleigh Choppers and muttonchop sideburns are neat. But they don't know about Dralon lounge suites and macrame. They never had to talk to someone whose life has been changed by Zen and the Art of Motorcycle Maintenance. They never had to sing Morning Has Broken in school assembly. It was rough then.
Look, here are some kids in 1975. They can't dance, their hair is too long and they all have really awful v-necks. Fortunately, some visitors from the future have arrived to teach them Cool. Their lives may never be the same again.
