I don't think that there will ever be a band that made that big of an impact on America than the Beatles. the reason why is because Rock And Roll has not been around for a while when the Beatles first came to america. So it was a big deal, especially for younger people. Most of the live performances show screaming teens going ape shit on over john and ringo. The thing is about them is that they where so likable. They where funny, sexy, and awesome at there instruments. No band  has really done what the Beatles did when they first came to USA. I think it will stay that way because rock and roll is kind of fading away. I know, it's sad and stupid. But you can kind of see that pop and hip hop is making its scene.
