Lonnie Rashid Lynn, Jr. was born on March 13, 1972 at the Chicago Osteopathic Hospital in Chicago's Hyde Park neighborhood, the son of educator Dr. Mahalia Ann Hines and former ABA basketball player turned youth counselor Lonnie Lynn Sr. He was raised in the Calumet Heights neighborhood. Lynn's parents divorced when he was six years old, resulting in his father moving to Denver, Colorado. This left Lynn to be raised by his mother; however, his father remained active in his life, and was able to get Lynn a job with the Chicago Bulls as a teenager.
Common was invited by First Lady Michelle Obama to appear at a poetry reading on May 11, 2011 at the White House. His poetry was found to be greatly influenced by Maya Angelou's works. This caused furor with the New Jersey State Police and their union, who disagreed with his lyrical content. The president of the New Jersey State Troopers Fraternal Association voiced concern to the White House. They cite the song "A Song For Assata" about a member of the Black Liberation Army and step-aunt of deceased rapper Tupac Shakur named Assata Shakur, previously known as Joanne Chesimard, who was convicted in 1977 of the first degree murder of New Jersey state trooper Werner Foerster. At another poetry reading, Common said, "flyers say 'free Mumia' on my freezer", a reference to Mumia Abu-Jamal, who was controversially convicted of killing Philadelphia Police Officer Daniel Faulkner in 1981. Common stated, "The one thing that shouldn't be questioned is my support for the police officers and troops that protect us every day." Jay Carney, the White House Press Secretary at the time, spoke for President Obama on the matter by saying the president does not support, but actually opposes, some of the kind of words and lyrics that have been written by Common and others. Even though the president does not support the lyrics in question, he believed that some reports were distorting what Mr. Lynn stands for more broadly. Common gave a single line response to the entire controversy: "I guess Sarah Palin and Fox News doesn't like me." Jon Stewart of Comedy Central's The Daily Show questioned Fox News' coverage of the controversy, saying that they "took the time to ignore Common's entire body of work, save for one poem he wrote in 2007 that they appear to misunderstand." Stewart also pointed out that in 2002, George W. Bush honored Johnny Cash, whose songs contain violent lyrics. Stewart further pointed out that Fox News itself offered positive coverage of Common's career in 2010, and that Sean Hannity, who criticized Common's White House invitation, is a friend of musician Ted Nugent, who in clips played on The Daily Show, used violent rhetoric in comments he made about President Obama and Hillary Clinton. Common later discussed the matter with Stewart during a September 14, 2011 appearance on the program. In September 2011, Common published his memoir, One Day It'll All Make Sense, through Atria Books. As the book details how his close relationship with his mother influenced his life, it is partially narrated by her.

What else can you tell me about his writings?

Answer the question at the end by quoting:

Pink Floyd were an English rock band formed in London in 1965. They achieved international acclaim with their progressive and psychedelic music. Distinguished by their use of philosophical lyrics, sonic experimentation, extended compositions, and elaborate live shows, they are one of the most commercially successful and influential groups in popular music history. Pink Floyd were founded by students Syd Barrett on guitar and lead vocals, Nick Mason on drums, Roger Waters on bass and vocals, and Richard Wright on keyboards and vocals.
Pink Floyd recorded The Dark Side of the Moon between May 1972 and January 1973, with EMI staff engineer Alan Parsons at Abbey Road. The title is an allusion to lunacy rather than astronomy. The band had composed and refined the material on Dark Side while touring the UK, Japan, North America and Europe. Producer Chris Thomas assisted Parsons. Hipgnosis designed the album's packaging, which included George Hardie's iconic refracting prism design on the cover. Thorgerson's Dark Side album cover features a beam of white light, representing unity, passing through a prism, which represents society. The resulting refracted beam of coloured light symbolises unity diffracted, leaving an absence of unity. Waters is the sole author of the album's lyrics. Released in March 1973, the LP became an instant chart success in the UK and throughout Western Europe, earning an enthusiastic response from critics. Each member of Pink Floyd except Wright boycotted the press release of The Dark Side of the Moon because a quadraphonic mix had not yet been completed, and they felt presenting the album through a poor-quality stereo PA system was insufficient. Melody Maker's Roy Hollingworth described side one as "utterly confused ... [and] difficult to follow", but praised side two, writing: "The songs, the sounds ... [and] the rhythms were solid ... [the] saxophone hit the air, the band rocked and rolled". Rolling Stone's Loyd Grossman described it as "a fine album with a textural and conceptual richness that not only invites, but demands involvement." Throughout March 1973, The Dark Side of the Moon featured as part of Pink Floyd's US tour. The album is one of the most commercially successful rock albums of all time; a US number 1, it remained on the Billboard chart for more than fourteen years, selling more than 45 million copies worldwide. In Britain, the album peaked at number 2, spending 364 weeks on the UK chart. Dark Side is the world's third best-selling album, and the twenty-first best-selling album of all time in the US. The success of the album brought enormous wealth to the members of Pink Floyd. Waters and Wright bought large country houses while Mason became a collector of expensive cars. Disenchanted with their US record company, Capitol Records, Pink Floyd and O'Rourke negotiated a new contract with Columbia Records, who gave them a reported advance of $1,000,000 (US$4,962,213 in 2017 dollars). In Europe, they continued to be represented by Harvest Records.

Did they ever tour internationally?
The band had composed and refined the material on Dark Side while touring the UK, Japan, North America and Europe.
