Some context: Booth was born in Bel Air, Maryland, into the English American theatrical Booth family. He was the illegitimate son of the famous actor, Junius Brutus Booth, an Englishman, who named Edwin after Edwin Forrest and Thomas Flynn, two of Junius' colleagues. He was the elder brother of John Wilkes Booth, himself a successful actor who gained notoriety as the assassin of President Lincoln. Nora Titone, in her book My Thoughts
Edwin Booth saved Abraham Lincoln's son, Robert, from serious injury or even death. The incident occurred on a train platform in Jersey City, New Jersey. The exact date of the incident is uncertain, but it is believed to have taken place in late 1864 or early 1865. Robert Lincoln recalled the incident in a 1909 letter to Richard Watson Gilder, editor of The Century Magazine.  The incident occurred while a group of passengers were late at night purchasing their sleeping car places from the conductor who stood on the station platform at the entrance of the car. The platform was about the height of the car floor, and there was of course a narrow space between the platform and the car body. There was some crowding, and I happened to be pressed by it against the car body while waiting my turn. In this situation the train began to move, and by the motion I was twisted off my feet, and had dropped somewhat, with feet downward, into the open space, and was personally helpless, when my coat collar was vigorously seized and I was quickly pulled up and out to a secure footing on the platform. Upon turning to thank my rescuer I saw it was Edwin Booth, whose face was of course well known to me, and I expressed my gratitude to him, and in doing so, called him by name.  Booth did not know the identity of the man whose life he had saved until some months later, when he received a letter from a friend, Colonel Adam Badeau, who was an officer on the staff of General Ulysses S. Grant. Badeau had heard the story from Robert Lincoln, who had since joined the Union Army and was also serving on Grant's staff. In the letter, Badeau gave his compliments to Booth for the heroic deed. The fact that he had saved the life of Abraham Lincoln's son was said to have been of some comfort to Edwin Booth following his brother's assassination of the president.

Some context: Tinariwen (Tamasheq: , with vowels , pronounced tinariwen "deserts", plural of tenere "desert") is a Grammy Award-winning group of Tuareg musicians from the Sahara Desert region of northern Mali. The band was formed in 1979 in Tamanrasset, Algeria, but returned to Mali after a cease-fire in the 1990s. The group first started to gain a following outside the Sahara region in 2001 with the release of The Radio Tisdas Sessions, and with performances at Festival au Desert in Mali and the Roskilde Festival in Denmark. Their popularity rose internationally with the release of the critically acclaimed Aman Iman in 2007.
Tinariwen was founded by Ibrahim Ag Alhabib, who at age four witnessed the execution of his father (a Tuareg rebel) during a 1963 uprising in Mali. As a child he saw a western film in which a cowboy played a guitar. Ag Alhabib built his own guitar out of a tin can, a stick and bicycle brake wire. He started to play old Tuareg and modern Arabic pop tunes. Ag Alhabib first lived in Algeria in refugee camps near Bordj Badji Mokhtar and in the deserts around the southern city of Tamanrasset, where he received a guitar from a local Arab man. Later, he resided with other Tuareg exiles in Libya and Algeria.  In the late 1970s, Ag Alhabib joined with other musicians in the Tuareg rebel community, exploring the radical chaabi protest music of Moroccan groups like Nass El Ghiwane and Jil Jilala; Algerian pop rai; and western rock and pop artists like Elvis Presley, Led Zeppelin, Carlos Santana, Dire Straits, Jimi Hendrix, Boney M, and Bob Marley. Ag Alhabib formed a group with Alhassane Ag Touhami and brothers Inteyeden Ag Ablil and Liya Ag Ablil in Tamanrasset, Algeria to play at parties and weddings. Ag Alhabib acquired his first real acoustic guitar in 1979. While the group had no official name, people began to call them Kel Tinariwen, which in the Tamashek language translates as "The People of the Deserts" or "The Desert Boys."  In 1980, Libyan ruler Muammar al-Gaddafi put out a decree inviting all young Tuareg men who were living illegally in Libya to receive full military training. Gaddafi dreamed of forming a Saharan regiment, made up of the best young Tuareg fighters, to further his territorial ambitions in Chad, Niger, and elsewhere. Ag Alhabib and his bandmates answered the call and received nine months of training. They answered a similar call in 1985, this time by leaders of the Tuareg rebel movement in Libya, and met fellow musicians Keddou Ag Ossade, Mohammed Ag Itlale (aka "Japonais"), Sweiloum, Abouhadid, and Abdallah Ag Alhousseyni. All sang and played guitar in various permutations. The musicians joined together in a collective (now known as Tinariwen) in order to create songs about the issues facing the Tuareg people, built a makeshift studio, and vowed to record music for free for anyone who supplied a blank cassette tape. The resulting homemade cassettes were traded widely throughout the Sahara region.  In 1989, the collective left Libya and moved to Ag Alhabib's home country of Mali, where he returned to his home village of Tessalit for the first time in 26 years. In 1990 the Tuareg people of Mali revolted against the government, with some members of Tinariwen participating as rebel fighters. After a peace agreement known as the Tamanrasset Accords was reached in January 1991, the musicians left the military and devoted themselves to music full-time. In 1992 some of the members of Tinariwen went to Abidjan, Cote d'Ivoire to record a cassette at JBZ studios. They played occasional gigs for far-flung Tuareg communities throughout the Sahara region, gaining word-of-mouth popularity among the Tuareg people.
