"There are only four people who knew what the Beatles were about anyway"

In this quote, Paul McCartney, among the members of the iconic band The Beatles, is reviewing the impact and legacy of their music. He recommends that despite their immense appeal and popularity, there were just 4 people who really understood the essence and meaning behind their music. This might be analyzed as a humble acknowledgement of the band's complexity and depth, in addition to an acknowledgment of the special bond and understanding shared between the four members.

Overall, McCartney's words use a glance into the inner functions and dynamics of one of the most influential bands in history.
