Task: Question Answering
Input (English): Passage: Music historians Schinder and Schwartz wrote of the transformation in popular music styles that took place between the 1950s and the 1960s. They said that the Beatles' influence cannot be overstated: having "revolutionised the sound, style, and attitude of popular music and opened rock and roll's doors to a tidal wave of British rock acts", the group then "spent the rest of the 1960s expanding rock's stylistic frontiers". Liam Gallagher and his group Oasis were among the many who acknowledged the band's influence; he identified Lennon as a hero. In 1999, he named his first child Lennon Gallagher in tribute. On National Poetry Day in 1999, the BBC conducted a poll to identify the UK's favourite song lyric and announced "Imagine" as the winner.In 1997, Yoko Ono and the BMI Foundation established an annual music competition programme for songwriters of contemporary musical genres to honour John Lennon's memory and his large creative legacy. Over $400,000 have been given through BMI Foundation's John Lennon Scholarships to talented young musicians in the United States.In a 2006 Guardian article, Jon Wiener wrote: "For young people in 1972, it was thrilling to see Lennon's courage in standing up to [US President] Nixon. That willingness to take risks with his career, and his life, is one reason why people still admire him today." For music historians Urish and Bielen, Lennon's most significant effort was "the self-portraits ... in his songs [which] spoke to, for, and about, the human condition."In 2013, Downtown Music Publishing signed a publishing administration agreement for the US with Lenono Music and Ono Music, home to the song catalogues of John Lennon and Yoko Ono respectively. Under the terms of the agreement, Downtown represents Lennon's solo works, including "Imagine", "Instant Karma (We All Shine On)", "Power to the People", "Happy Xmas (War Is Over)", "Jealous Guy", "(Just Like) Starting Over" and others.
Lennon continues to be mourned throughout the world and has been the subject of numerous memorials and tributes. In 2002, the airport in Lennon's home town was renamed the Liverpool John Lennon Airport. On what would have been Lennon's 70th birthday in 2010, Cynthia and Julian Lennon unveiled the John Lennon Peace Monument in Chavasse Park, Liverpool. The sculpture, entitled Peace & Harmony, exhibits peace symbols and carries the inscription "Peace on Earth for the Conservation of Life · In Honour of John Lennon 1940–1980". In December 2013, the International Astronomical Union named one of the craters on Mercury after Lennon.
