Okay, I've go to admit that maybe after 1969 to early 70's, I was worried about the boys. 

Only because their hairstyle was so weird around that time. And okay, Paul's mullet was okay, but it wasn't the toppermost of the poppermost that his hair could have been. Ever one of those guys have hair potential and Paul was literally running away from it for a while. XD

But I thoroughly enjoyed 1966 hairstyle. I dunno, maybe I like my men with slightly longer hair than usual. 

BUT WITH RESTRICTIONS! LIKE, BEARDS THAT AREN'T LOOKING TO BE THEIR OWN PERSON . . . looking at you John.

My favourite out of that year is George. Don't question me on that, but his hair really complimented his face and seriously, that hair is great.
