Who is the top singer in the Beatles?

The leader of The Beatles changed through their history. As the founder of the band, John Lennon was widely seen as the leader in their early days - until Ringo joined the band (around 5 years after the band started), Lennon was also the oldest member by over a year.

In the recording studio, Paul McCartney tended to be more "in charge" of the band. After they stopped touring in 1966, he became more the leader of the band - this caused some resentment from the other Beatles.
