I actually think it'd be pretty difficult not to know the individual members of the Beatles.
Their names are so commonly thrown around..
Most overrated bands are.
I actually can't think of another band whose names are commonly used for many different examples or reasons. (Honestly, I don't know any other band where I know the name of every member)
And yes, I am ignoring the overrated comment since arguments about Beatles are stupid.
One side has one opinion, the other is basically the complete opposite. No point in arguing over something that isn't changing.
