Problem: 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".

Problem: Nehemiah Curtis "Skip" James (June 9, 1902 - October 3, 1969) was an American Delta blues singer, guitarist, pianist and songwriter. His guitar playing is noted for its dark, minor-key sound, played in an open D-minor tuning with an intricate fingerpicking technique. James first recorded for Paramount Records in 1931, but these recordings sold poorly, having been released during the Great Depression, and he drifted into obscurity. After a long absence from the public eye, James was "rediscovered" in 1964 by blues enthusiasts, helping further the blues and folk music revival of the 1950s and early 1960s.

For the next thirty years, James recorded nothing and performed sporadically. He was virtually unknown to listeners until about 1960. In 1964, blues enthusiasts John Fahey, Bill Barth, and Henry Vestine found him in a hospital in Tunica, Mississippi. According to Calt, the "rediscovery" of both James and Son House at virtually the same time was the start of the blues revival in the United States. In July 1964 James and other rediscovered musicians appeared at the Newport Folk Festival. Several photographs by the blues promoter Dick Waterman captured this performance, James's first in over 30 years. After that James recorded for Takoma Records, Melodeon Records, and Vanguard Records and performed at various engagements until his death in 1969. More of James's recordings have been available since his death than were available during his lifetime. His 1931 recordings and several of his recordings and concerts from the 1960s have been reissued on numerous compact discs, in and out of print. His songs were not initially recorded as frequently as those of other rediscovered blues musicians. However, the British rock band Cream recorded "I'm So Glad", providing James with the only windfall of his career. Subsequently, Cream's adaptation was recorded by other groups. James' "22-20" inspired for the name for the English group 22-20s and the British post-rock band Hope of the States released a song partially about the life of James, entitled "Nehemiah", which reached number 30 on the UK Singles Chart. In 2004, Wim Wenders directed the film The Soul of a Man (the second part of The Blues, a series produced by Martin Scorsese), focusing on the music of Blind Willie Johnson, J.B. Lenoir and James. Because James had not been not filmed before the 1960s, Keith B. Brown played the part of the young James in the documentary.

Problem: Yusuf Islam (born Steven Demetre Georgiou; 21 July 1948), commonly known by his former stage name Cat Stevens, is a British singer-songwriter and multi-instrumentalist. His 1967 debut album reached the top 10 in the UK, and the album's title song "Matthew and Son" charted at number 2 on the UK Singles Chart. Stevens' albums Tea for the Tillerman (1970) and Teaser and the Firecat (1971) were both certified triple platinum in the US by the RIAA. His musical style consists of folk, pop, rock, and Islamic music.

Immediately following the September 11 attacks on the United States, he said: I wish to express my heartfelt horror at the indiscriminate terrorist attacks committed against innocent people of the United States yesterday. While it is still not clear who carried out the attack, it must be stated that no right-thinking follower of Islam could possibly condone such an action. The Qur'an equates the murder of one innocent person with the murder of the whole of humanity. We pray for the families of all those who lost their lives in this unthinkable act of violence as well as all those injured; I hope to reflect the feelings of all Muslims and people around the world whose sympathies go out to the victims of this sorrowful moment. He appeared on videotape on a VH1 pre-show for the October 2001 Concert for New York City, condemning the attacks and singing his song "Peace Train" for the first time in public in more than 20 years, as an a cappella version. He also donated a portion of his box-set royalties to the fund for victims' families, and the rest to orphans in underdeveloped countries. During the same year, he dedicated time and effort in joining the Forum Against Islamophobia and Racism, an organisation that worked towards battling misconceptions and acts against others because of their religious beliefs or their racial identity (or both), after many Muslims reported a backlash against them due in part to the grief caused by the events in the United States on 11 September.
