That whole era can be summed up by the song "I went thru the desert on a horse with no name..." You listen to that song and say, what the hell is that all about? Weird shit.
I can't remember which comedian does it, but there's some young comic who has a whole bit about the idiocy of that song. One of the lines is something like, "Dude, you've been riding across the desert for nine days with nothing to do. NAME the damn HORSE!!!"
