Answer the question at the end by quoting:

James Buchanan Jr. was born in a log cabin in Cove Gap, Pennsylvania (now Buchanan's Birthplace State Park), in Franklin County, on April 23, 1791, to James Buchanan, Sr. (1761-1821), a businessman, merchant, and farmer, and Elizabeth Speer, an educated woman (1767-1833). His parents were both of Ulster Scottish descent, the father having emigrated from Milford, County Donegal, Ireland, in 1783. One of eleven siblings, Buchanan was the oldest child in the family to survive infancy.
The Civil War erupted within two months of Buchanan's retirement. He supported the United States, writing to former colleagues that "the assault upon Sumter was the commencement of war by the Confederate states, and no alternative was left but to prosecute it with vigor on our part". He also wrote a letter to his fellow Pennsylvania Democrats, urging them to "join the many thousands of brave & patriotic volunteers who are already in the field". Buchanan spent most of his remaining years defending himself from public blame for the Civil War, which was even referred to by some as "Buchanan's War". He began receiving angry and threatening letters daily, and stores displayed Buchanan's likeness with the eyes inked red, a noose drawn around his neck and the word "TRAITOR" written across his forehead. The Senate proposed a resolution of condemnation which ultimately failed, and newspapers accused him of colluding with the Confederacy. His former cabinet members, five of whom had been given jobs in the Lincoln administration, refused to defend Buchanan publicly. Initially so disturbed by the attacks that he fell ill and depressed, Buchanan finally began defending himself in October 1862, in an exchange of letters between himself and Winfield Scott that was published in the National Intelligencer newspaper. He soon began writing his fullest public defense, in the form of his memoir Mr. Buchanan's Administration on the Eve of Rebellion, which was published in 1866. Buchanan caught a cold in May 1868, which quickly worsened due to his advanced age. He died on June 1, 1868, from respiratory failure at the age of 77 at his home at Wheatland and was interred in Woodward Hill Cemetery in Lancaster.

Some context: Brian Wayne Transeau (born October 4, 1971), better known by his stage name BT, is an American music producer, composer, technologist, audio technician, multi-instrumentalist, singer, and songwriter. An artist in the electronica music genre, he is credited as a pioneer of the trance and intelligent dance music styles that paved the way for EDM, and for "stretching electronic music to its technical breaking point." He also creates music within many other styles, such as classical, film composition and bass music. BT is also known for pioneering the stutter edit.
In the early years of BT's career, he became a pioneering artist in the trance genre, this despite the fact that he doesn't consider himself a DJ, since he infrequently spins records and comes from an eclectic music background. He was creating trance music before it was known by that name. When he started out, such common elements as a build, breakdown and drop were unclassified. BT's was a unique interpretation of what electronic music could be. His first trance recordings, "A Moment of Truth" and "Relativity", became hits in dance clubs in the UK. His productions were not yet popular in the US, and he was initially unaware that he had become popular across the Atlantic, where UK DJs like Sasha were regularly spinning his music for crowds. Sasha bought BT a ticket to London, where BT witnessed his own success in the clubs, with several thousand clubbers responding dramatically when Sasha played BT's song. He also met Paul Oakenfold, playing him tracks that would make up his first album. He was quickly signed to Oakenfold's record label, a subsidiary of Warner Brothers. BT's 1995 debut album Ima, released on Oakenfold's label, was a progressive house effort. The opening track, "Nocturnal Transmission", was featured in The Fast and the Furious. The album also featured a song with Vincent Covello. Blending house beats with sweeping New Age sounds, Ima helped to create the trance sound. "Ima (Jin )" is the Japanese word for "now". BT has stated that it also means many other things and that the intention of the album is to have a different effect for everyone. Following the release of Ima, BT began traveling to England regularly. It was during this time that he met Tori Amos. They would collaborate on his song "Blue Skies", which reached the number one spot on Billboard magazine's Dance Club Songs chart in January 1997. This track helped expand BT's notability beyond Europe, into North America. He soon began to produce songs for well-known artists such as Sting, Madonna, Seal, Sarah McLachlan, NSYNC, Britney Spears, Diana Ross and Mike Oldfield.

Eric Stefani and John Spence met at a Dairy Queen and had talked about getting a group together to play music. Eric got a keyboard and gathered some players together to practice. The practice included Eric Stefani (keyboards), Gwen Stefani (backing vocals), John Spence (lead vocals), Jerry McMahon (guitar), Chris Leal (bass), Chris Webb (drums), Gabriel Gonzalez & Alan Meade (trumpet) and Tony Meade (saxophone). They practiced in Eric's parents' garage. Tony Kanal went to one of the band's early shows and soon joined the band as its bassist. After initially rejecting her advances, he began dating Gwen, but they kept their relationship secret for a year, feeling that it was an unspoken rule that no one in the band dates her. Paul Caseley (trombone) also joined the band in 1987. Eric Carpenter (saxophone) joined the horn section soon after. In December 1987, Spence committed suicide several days before the band was to play a gig at The Roxy Theatre for record industry employees. No Doubt disbanded but decided to regroup after several weeks with Alan Meade taking over vocals. When Meade left the band, Gwen replaced him as lead singer, and No Doubt continued to develop a live following in California. In early 1988, Tom Dumont left Rising, a heavy metal band of which he was a member with his sister, stating that local metal bands "were into drinking, wearing Spandex" but that he wanted to focus on music. He joined No Doubt and replaced Jerry McMahon as the band's guitarist. Adrian Young replaced Chris Webb as the drummer the following year. During this time period, No Doubt played gigs at local colleges, Fender's Grand Ballroom, The Whisky, The Roxy, many shows with The Untouchables, Fishbone, and a show with the Red Hot Chili Peppers at Cal State Long Beach. Caseley left No Doubt in July 1989 for the US Navy Band.
