Pete Best is discharged from the Beatles, to be replaced two days later by Ringo Starr.

Sir Richard Starkey (born 7 July 1940), known professionally as Ringo Starr, is an English musician, singer, songwriter and actor who achieved international fame as the drummer for the Beatles. Starr occasionally sang lead vocals with the group, usually for one song on each album, including "Yellow Submarine" and "With a Little Help from My Friends". He also wrote and sang the Beatles songs "Don't Pass Me By" and "Octopus's Garden", and is credited as a co-writer of others.

Starr was afflicted by life-threatening illnesses during childhood, with periods of prolonged hospitalisation. He briefly held a position with British Rail before securing an apprenticeship as a machinist at a Liverpool school equipment manufacturer. Soon afterwards, Starr became interested in the UK skiffle craze and developed a fervent admiration for the genre. In 1957, he co-founded his first band, the Eddie Clayton Skiffle Group, which earned several prestigious local bookings before the fad succumbed to American rock and roll around early 1958. When the Beatles formed in 1960, Starr was a member of another Liverpool group, Rory Storm and the Hurricanes. After achieving moderate success in the UK and Hamburg, he quit the Hurricanes when he was asked to join the Beatles in August 1962, replacing Pete Best.

In addition to the Beatles' films, Starr has acted in numerous others. After the band's break-up in 1970, he released several successful singles including the US top-ten hit "It Don't Come Easy", and number ones "Photograph" and "You're Sixteen". His most successful UK single was "Back Off Boogaloo", which peaked at number two. He achieved commercial and critical success with his 1973 album Ringo, which was a top-ten release in both the UK and the US. Starr has featured in numerous documentaries, hosted television shows, narrated the first two series of the children's television program Thomas & Friends and portrayed "Mr. Conductor" during the first season of the PBS children's television series Shining Time Station. Since 1989, he has toured with thirteen variations of Ringo Starr & His All-Starr Band.

Starr's playing style, which emphasised feel over technical virtuosity, influenced many drummers to reconsider their playing from a compositional perspective. He also influenced various modern drumming techniques, such as the matched grip, tuning the drums lower, and using muffling devices on tonal rings. In his opinion, his finest recorded performance was on the Beatles' "Rain". In 1999, he was inducted into the Modern Drummer Hall of Fame. In 2011, Rolling Stone readers named him the fifth-greatest drummer of all time. He was inducted twice into the Rock and Roll Hall of Fame, as a Beatle in 1988 and as a solo artist in 2015, and appointed a Knight Bachelor in the 2018 New Year Honours for services to music. In 2020, he was cited as the wealthiest drummer in the world, with a net worth of $350 million.

Randolph Peter Best (né Scanland; born 24 November 1941) is an English musician known as the drummer of the English rock band the Beatles immediately before the band achieved worldwide fame. Fired from the group in 1962 after playing drums as a Beatle for the previous two years in Germany and England, he started his own band, the Pete Best Four. He later joined and started many other bands over the years. He is one of several people who have been referred to as the Fifth Beatle.

Best's mother, Mona Best (1924–1988), opened the Casbah Coffee Club in the cellar of the Bests' house in Liverpool. The Beatles (at the time known as the Quarrymen) played some of their first concerts at the club. The Beatles invited Best to join the band on 12 August 1960, on the eve of the group's first Hamburg season of club dates. Ringo Starr eventually replaced Best on 16 August 1962, when the group's manager, Brian Epstein, fired Best at the request of John Lennon, Paul McCartney and George Harrison following the band's first recording session. Over 30 years later, Best received a major monetary payout for his work with the Beatles after the release of their 1995 compilation of their early recordings on Anthology 1; Best played the drums on a number of the album's tracks, including the Decca auditions.

After working in a number of commercially unsuccessful groups, Best gave up the music industry to work as a civil servant for 20 years before starting the Pete Best Band.
