I talked to someone about this before and someone said that John would probably be punk or goth because of his views on life, his musical tastes as we know them, and his attitude he had towards life. I tend to agree with this. I would probably say emo, but knowing John back in the 50's, he'd probably still be tough and wouldn't want to show his EMOtions.
As for Paul, he once said that he liked Emeniem for his courage to speak out and didn't care what others thought. So I think that he'd be into a little of that as well as some poppish/romance songs, knowing Paul and all. He'd probably be the school hotty that every girl loves and would probably have a bunch of girl friends in his time--lots of fun might I add.
George, well... I think he'd be into the Indie stuff as well.
Ringo... Would he have been the outcast? He said he liked Country Western before it was even in, so I think he'd be into that. He also said he liked Emeniem, so with that in mind, he'd be in the same page as that too.
I hope to get more responses. This would be quite interesting.
