Problem: Background: Mumford & Sons are a British band formed in 2007. The band consists of Marcus Mumford (lead vocals, electric guitar, acoustic guitar, drums), Ben Lovett (vocals, keyboard, piano, synthesizer), Winston Marshall (vocals, electric guitar, banjo) and Ted Dwane (vocals, bass guitar, double bass). Mumford & Sons have released three studio albums: Sigh No More (2009), Babel (2012) and Wilder Mind (2015).
Context: Mumford & Sons released their second studio album Babel on 24 September 2012, with a track listing of 12 songs, and a deluxe edition containing three exclusive songs. The lead single "I Will Wait" premiered on Zane Lowe's BBC Radio 1 show on 7 August. On 29 August 2012, Mumford & Sons recorded their concert at Red Rocks Amphitheatre in Colorado. The Concert was later released on DVD, Vinyl and on iTunes as "Road to Red Rocks". The performance of "I Will Wait" from the concert was released ahead of the DVD on 9 September as the band's official video for the song. On 22 September 2012, the band performed two songs from the new album, "I Will Wait" and "Below My Feet", on Saturday Night Live.  Babel debuted at number one on the UK Albums Chart and the US Billboard 200. It became the fastest selling album of 2012 in the UK, selling over 158,000 copies in its first week, and was the biggest selling debut of any album in 2012 in the US, selling 600,000 in its first week, and over a million worldwide. In December 2012, Winston Marshall told NME that the band was rehearsing and writing for their next album.  The first phase of a 2013 world tour in support of Babel was released in November 2012. Their Gentlemen of the Road tour continued through 2013. After performing two shows on 8 & 9 June 2013 at the Austin360 Amphitheater in Austin, Texas, bassist Ted Dwane checked into a hospital the next day. Surgeons found a blood clot on the surface of his brain and performed surgery to remove it. Heeding medical advice to aid Dwane's recovery, the band cancelled the rest of its Summer Stampede Tour, including performances at the 2013 Bonnaroo Music Festival and returned to the UK. Dwane's surgery was successful, and his recovery was such that the band were able to headline the 2013 Glastonbury Festival on 30 June, with the band receiving acclaim for their performance.  After first including select stopover cities in their 2012 Tour, the band again selected five cities in Canada, the UK and US to host a two-day festival with shows on multiple stages as well as various other activities and performances. The first stopover of the 2013 Gentleman of the Road tour was in Lewes, East Sussex, from 19 to 20 July. Next was Simcoe, Ontario from 23 to 24 August, followed by Troy, Ohio from 30 to 31 August. The band rounded out their tour with stopovers in Guthrie, Oklahoma on 6 and 7 September and finally St. Augustine, Florida on 13 and 14 September. The Vaccines, Edward Sharpe & the Magnetic Zeros, Vampire Weekend, Old Crow Medicine Show, Yacht Club DJs, Alabama Shakes and various other bands also performed at many of the stopovers throughout the tour.  After the end of the Babel tour, Mumford and Sons took a five-month break before returning to the studio in February 2014 to start work on their third album.
Question: Did they write their own music?
Answer: 

Background: Howard Brush Dean III (born November 17, 1948) is an American physician, author and retired politician who served as the 79th Governor of Vermont from 1991 to 2003 and Chair of the Democratic National Committee (DNC) from 2005 to 2009. Dean was a candidate for the Democratic nomination in the 2004 presidential election. His implementation of the fifty-state strategy as head of the DNC is credited with the Democratic victories in the 2006 and 2008 elections. Afterward, he became a political commentator and consultant to McKenna Long & Aldridge, a law and lobbying firm.
Context: Dean graduated from Yale University with a Bachelor of Arts in political science in 1971. As a freshman, he requested specifically to room with an African-American. The university housing office complied and Dean roomed with two Southern black students and one white student from Pennsylvania. One of Dean's roommates was Ralph Dawson, the son of a sheet metal worker in Charleston, South Carolina and today a New York City labor lawyer. Dawson said of Dean:  Unless you operated from a stereotypic understanding of the Yale white boy as rich, you wouldn't know that about Howard.... When it came to race- and I don't know whether this was a function of intent or just came naturally- Howard was not patronizing in any way. He was willing to confront in discussion what a lot of white students weren't. He would hold his ground. He would respect that I knew forty-two million times more about being black than he did. But that didn't mean he couldn't hold a view on something relating to civil rights that would be as valid as mine. There were lots of well-meaning people at Yale who wanted you to understand that they understood your plight; you'd get into a conversation and they would yield too soon, so we didn't get the full benefit of the exchange. Howard very much thought he was capable of working an issue through. He was inquisitive. And when he came to a conclusion he would be as strong as anybody else. I don't think he's stubborn. He's a guy who's always been comfortable in his own skin. That's something you still see in him today, and it gets him into some degree of controversy.  Though eventually eligible to be drafted into the military, he received a deferment for an unfused vertebra. He explained to Tim Russert on Meet the Press, "I was really in no hurry to join the military." He briefly tried a career as a stockbroker before deciding on a career in medicine, completing pre-medicine classes at Columbia University. In 1974, Dean's younger brother Charlie, who had been traveling through southeast Asia at the time, was captured and killed by Laotian guerrillas, a tragedy widely reported to have an enormous influence in Dean's life; he wore his brother's belt every day of his presidential campaign.
