By 1964, John Lennon, Paul McCartney, George Harrison, and Ringo Starr had been working together in The Beatles for two years. Lennon, McCartney, and Harrison had been in a band together for much longer than this, but Starr was a latecomer to the group. He felt left out when he first joined the band, but by 1964, he had settled in. This changed when the rest of the band went on tour without him. He explained that he worried his bandmates didn’t love him anymore.

Ringo Starr stayed behind when The Beatles went on their 1964 tour
In 1964, Starr was hospitalized with tonsillitis. The Beatles were preparing to embark on a world tour, which meant they either had to wait for Starr or replace him. They chose to do the latter.
