Question:
The Beatles were an English rock band formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential music band. Rooted in skiffle, beat and 1950s rock and roll, the Beatles later experimented with several musical styles, ranging from pop ballads and Indian music to psychedelia and hard rock, often incorporating classical elements and unconventional recording techniques in innovative ways. In 1963 their enormous popularity first emerged as "Beatlemania"; as the group's music grew in sophistication, led by primary songwriters Lennon and McCartney, the band were integral to pop music's evolution into an art form and to the development of the counterculture of the 1960s.
In Icons of Rock: An Encyclopedia of the Legends Who Changed Music Forever, Scott Schinder and Andy Schwartz describe the Beatles' musical evolution: In their initial incarnation as cheerful, wisecracking moptops, the Fab Four revolutionised the sound, style, and attitude of popular music and opened rock and roll's doors to a tidal wave of British rock acts. Their initial impact would have been enough to establish the Beatles as one of their era's most influential cultural forces, but they didn't stop there. Although their initial style was a highly original, irresistibly catchy synthesis of early American rock and roll and R&B, the Beatles spent the rest of the 1960s expanding rock's stylistic frontiers, consistently staking out new musical territory on each release. The band's increasingly sophisticated experimentation encompassed a variety of genres, including folk-rock, country, psychedelia, and baroque pop, without sacrificing the effortless mass appeal of their early work. In The Beatles as Musicians, Walter Everett describes Lennon and McCartney's contrasting motivations and approaches to composition: "McCartney may be said to have constantly developed - as a means to entertain - a focused musical talent with an ear for counterpoint and other aspects of craft in the demonstration of a universally agreed-upon common language that he did much to enrich. Conversely, Lennon's mature music is best appreciated as the daring product of a largely unconscious, searching but undisciplined artistic sensibility." Ian MacDonald describes McCartney as "a natural melodist - a creator of tunes capable of existing apart from their harmony". His melody lines are characterised as primarily "vertical", employing wide, consonant intervals which express his "extrovert energy and optimism". Conversely, Lennon's "sedentary, ironic personality" is reflected in a "horizontal" approach featuring minimal, dissonant intervals and repetitive melodies which rely on their harmonic accompaniment for interest: "Basically a realist, he instinctively kept his melodies close to the rhythms and cadences of speech, colouring his lyrics with bluesy tone and harmony rather than creating tunes that made striking shapes of their own." MacDonald praises Harrison's lead guitar work for the role his "characterful lines and textural colourings" play in supporting Lennon and McCartney's parts, and describes Starr as "the father of modern pop/rock drumming".

What songs did they come up with?

Answer:

input: Sinatra attempted to pursue an acting career in Hollywood in the early 1940s. While films appealed to him, being exceptionally self-confident, he was rarely enthusiastic towards his own acting, once remarking that "pictures stink". Sinatra made his film debut in 1941, performing in an uncredited sequence in Las Vegas Nights, singing "I'll Never Smile Again" with Tommy Dorsey's The Pied Pipers. In 1943 he had a cameo role along with Duke Ellington and Count Basie in Charles Barton's Reveille with Beverly, making a brief appearance singing "Night and Day". The following year he was given his leading roles in Higher and Higher and Step Lively for RKO Pictures. In 1945, Metro-Goldwyn-Mayer cast Sinatra opposite Gene Kelly and Kathryn Grayson in the Technicolor musical Anchors Aweigh, in which he played a sailor on leave in Hollywood for four days. A major success, it garnered several Academy Award wins and nominations, and the song "I Fall in Love Too Easily", sung by Sinatra in the film, was nominated for the Academy Award for Best Original Song. In 1946, Sinatra briefly appeared at the end of Richard Whorf's commercially successful Till the Clouds Roll By, a Technicolor musical biopic of Jerome Kern, in which he sang "Ol' Man River. In 1949, Sinatra co-starred with Gene Kelly in the Technicolor musical Take Me Out to the Ball Game, a film set in 1908, in which Sinatra and Kelly play baseball players who are part-time vaudevillians. He teamed up with Kelly for a third time in On the Town, playing a sailor on leave in New York City. Today the film is rated very highly by critics, and in 2006 it ranked No. 19 on the American Film Institute's list of best musicals. Both Double Dynamite (1951), an RKO Irving Cummings comedy produced by Howard Hughes, and Joseph Pevney's Meet Danny Wilson (1952) failed to make an impression. The New York World Telegram and Sun ran the headline "Gone on Frankie in '42; Gone in '52".

Answer the question at the end by quoting:

Andrew "Rube" Foster (September 17, 1879 - December 9, 1930) was an American baseball player, manager, and executive in the Negro leagues. He was elected to the Baseball Hall of Fame in 1981. Foster, considered by historians to have been perhaps the best African-American pitcher of the first decade of the 1900s, also founded and managed the Chicago American Giants, one of the most successful black baseball teams of the pre-integration era. Most notably, he organized the Negro National League, the first long-lasting professional league for African-American ballplayers, which operated from 1920 to 1931.
In 1907, Foster's manager Sol White published his Official Baseball Guide: History of Colored Baseball, with Foster contributing an article on "How to Pitch." However, before the season began, he and several other stars (including, most importantly, the outfielder Pete Hill) left the Philadelphia Giants for the Chicago Leland Giants, with Foster named playing manager. Under his leadership, the Lelands won 110 games (including 48 straight) and lost only ten, and took the Chicago City League pennant. The following season the Lelands tied a national championship series with the Philadelphia Giants, each team winning three games. Foster suffered a broken leg in July 1909, but rushed himself back into the lineup in time for an October exhibition series against the Chicago Cubs. Foster, pitching the second game, squandered a 5-2 lead in the ninth inning, then lost the game on a controversial play when a Cubs runner stole home while Foster was arguing with the umpire. The Lelands lost the series, three games to nothing. The Lelands also lost the unofficial western black championship to the St. Paul Colored Gophers. In 1910, Foster wrested legal control of the team from its founder, Frank Leland. He proceeded to put together the team he later considered his finest. He signed John Henry Lloyd away from the Philadelphia Giants; along with Hill, second baseman Grant Johnson, catcher Bruce Petway, and pitchers Frank Wickware and Pat Dougherty, Lloyd sparked the Lelands to a 123-6 record (with Foster himself contributing a 13-2 record on the mound).

Did the Leland Giants win any championships beyond the Chicago City pennant?
The following season the Lelands tied a national championship series with the Philadelphia Giants, each team winning three games.
