Question: The fifth Beatle is an informal title that various commentators in the press and entertainment industry have applied to people who were at one point a member of the Beatles, or who had a strong association with the "Fab Four" (John Lennon, Paul McCartney, George Harrison, and Ringo Starr) during the group's existence. The "fifth Beatle" claims first appeared in the press immediately upon the band's rise to global fame in 1963-64. The members have offered their own beliefs of the "fifth Beatle": Lennon was critical of individuals who claimed credit for the Beatles' success, including the individual Beatles themselves, saying in his 1970 interview with Jann Wenner, "I'm not the Beatles. I'm me.

Brian Epstein, the band's manager from 1961 until his death in 1967, was instrumental in the Beatles' rise to global fame. Epstein "discovered" the band in Liverpool, saw their potential, and never wavered in his faith and commitment to them. He purposefully restricted his oversight of the band, limiting himself to business matters and public image, and gave the band free creative rein in their music. Epstein also doggedly sought a recording contract for the band in London at a crucial moment in their career, fighting their perception as provincial "northern" musicians. Epstein's death in essence marked the beginning of the Beatles' dissolution, as Lennon admitted later. Because he was not creatively involved with the band, Epstein was only infrequently called the "fifth Beatle", but over the years he and producer George Martin have clearly been recognised as the inner circle members who most profoundly affected the band's career. In an interview in the 1990s describing Epstein's involvement in the band's rise to fame, Martin declared "He's the fifth Beatle, if there ever was one." McCartney summarized the importance of Epstein to the Beatles when he was interviewed in 1997 for a BBC documentary about Epstein. He stated: "If anyone was the fifth Beatle, it was Brian." In 2013 Epstein was the subject of a graphic novel entitled The Fifth Beatle by Vivek Tiwary. The book was released in November and spent several weeks on The New York Times best-seller list, reaching no. 1 in its third week of release.

Problem: The Ronettes () were an American girl group from New York City. One of the most popular groups from the 1960s, they placed nine songs on the Billboard Hot 100, five of which became Top 40 hits. The trio from Spanish Harlem, New York, consisted of lead singer Veronica Bennett (later known as Ronnie Spector), her older sister Estelle Bennett, and their cousin Nedra Talley. Among the Ronettes' most famous songs are "Be My Baby",

As the British Invasion took full force on the American music scene in 1964, the Ronettes were one of the few groups that were able to maintain their relevance. When they toured the UK in January 1964, they had been asked by John Lennon to accompany the Beatles on their flight to America on February 7, 1964, but Spector denied them the opportunity to do so. Instead, throughout 1964, the group appeared on numerous television shows such as Shindig!, American Bandstand, Hullabaloo, and British TV show Ready, Steady, Go! As the popularity of other groups such as The Crystals, The Marvelettes, and The Angels began to wane, that of the Ronettes continued to grow. In the summer of 1964, Ronnie went into the studio to record her lead on the group's next single, "Walking in the Rain". She later recalled that the writers - Phil Spector, Barry Mann, and Cynthia Weil - were still adjusting the lyrics right up to the minute she recorded it. Ronnie recalled Phil placing headphones on her and telling her to listen closely. "Everything was quiet," she later wrote, "Then all of a sudden I heard a low rumble, like there was thunder coming from every corner of the room." The thunder was used for the introduction and was featured prominently throughout the remainder of the song, the only one of which Ronnie recorded in a single take. "Walking in the Rain" became the group's most successful single since "Be My Baby" (released over a year earlier) and peaked at #23 on the Billboard Hot 100. Following the successful release of "Walking in the Rain", Philles Records released the group's first studio album, Presenting the Fabulous Ronettes featuring Veronica, in late 1964. The album proved to be slightly successful, peaking at #96 on the Billboard charts, but it is notable for being the first evidence of Phil Spector publicly promoting lead singer Veronica "Ronnie" Bennett over Estelle Bennett and Nedra Talley. Every Ronettes single after this referred to the group as "The Ronettes featuring Veronica" on the record labels.

When was it released?

Answer with quotes: "Walking in the Rain" became the group's most successful single since "Be My Baby" (released over a year earlier) and peaked at #23 on the Billboard Hot 100.
