Joshua King (16 January 1798 Lowick, near Ulverston, in Lancashire, England – 1 September 1857 President's Lodge, Queens' College, Cambridge) was the Lucasian Professor of Mathematics at the University of Cambridge from 1839 to 1849.

"Joshua King came to Cambridge from Hawkshead Grammar School. It was soon evident that the school had produced someone of importance. He became Senior Wrangler, and his reputation in Cambridge was immense. It was believed that nothing less than a Second Newton had appeared. They expected his work as a mathematician to make an epoch in the science. At an early age he became President of Queens’; later, he was Lucasian Professor. He published nothing; in fact, he did no mathematical work. But as long as he kept his health, he was an active and prominent figure in Cambridge, and he maintained his enormous reputation. When he died, it was felt that the memory of such an extraordinary man should not be permitted to die out, and his papers should be published. So his papers were examined, and nothing whatever worth publishing was found."

Joshua (Hebrew: יְהוֹשֻׁעַ‎‎ Yĕhôshúa‘; Greek: Ἰησοῦς, Arabic: يوشع بن نون‎ Yūshaʿ ibn Nūn), is a figure in the Torah, being one of the spies for Israel (Num 13-14) and in few passages as Moses's assistant. He is the central character in the Hebrew Bible's Book of Joshua. According to the books Exodus, Numbers and Joshua, he became the leader of the Israelite tribes after the death of Moses; his name was Hoshe'a the son of Nun, of the tribe of Ephraim, but Moses called him Yehoshu'a (Joshua) (Numbers 13:16) the name by which he is commonly known; and he was born in Egypt prior to the Exodus, and was probably the same age as Caleb, with whom he is occasionally associated.

He was one of the twelve spies of Israel sent by Moses to explore the land of Canaan. (Numbers 13:1-16) After the death of Moses, he led the Israelite tribes in the conquest of Canaan, and allocated the land to the tribes. According to Biblical chronology, Joshua lived between 1500–1390 BCE, or sometime in the late Bronze Age. According to Joshua 24:29, Joshua died at the age of 110.

George "Buddy" Guy (born July 30, 1936) is an American blues guitarist and singer. Critically acclaimed, he is a pioneer of the Chicago blues sound and has served as an influence to some of the most notable musicians of his generation. "A key influence on Eric Clapton, Jimi Hendrix and Stevie Ray Vaughan, Buddy Guy put the Louisiana hurricane in 1960s electric Chicago blues as a member of Muddy Waters' band and as a house guitarist at Chess Records. A native of the Baton Rouge area, he combined a blazing modernism with a fierce grip on his roots, playing frantic leads heavy with swampy funk on Howlin' Wolf's 'Killing Floor' and Koko Taylor's 'Wang Dang Doodle' as well as on his own Chess sides and the fine series of records he made with harp man Junior Wells. One of the last active connections to the golden age of Chess, Guy still plays with his original fire."

Ranked thirtieth in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time", Guy is known for his showmanship on stage: playing his guitar with drumsticks or strolling into the audience while playing solos. His song "Stone Crazy" was ranked seventy-eighth in list of the 100 Greatest Guitar Songs of All Time also of Rolling Stone.

Quinn Sullivan (born March 26, 1999) is an American musician from New Bedford, Massachusetts who plays the guitar and sings. He released his debut album Cyclone in 2011 and is on his way to releasing a follow up album soon this coming year.

Sullivan began taking guitar lessons at age five. He has studied with Brian Cass of The Overclock Orchestra and the Toe Jam Puppet Band as well as Stan Belmarce. The first original song he wrote with Chris Waters was titled "Sing, Dance, Clap Your Hands". Sullivan first gained national media attention at age six when he appeared on The Ellen Degeneres Show. He garnered more attention when Buddy Guy asked him to come on stage and play during a performance at the Zeiterion Theater in New Bedford, Massachusetts in 2007.

Quinn has since performed on stage with Guy as well as with B.B. King and has played in venues such as the Beacon Theatre in New York City, the Orpheum Theatre in Boston, and Buddy Guy’s Legends in Chicago. In 2008, Sullivan appeared on The Oprah Winfrey Show and was featured on NBC's The Today Show in July 2009. In 2009, Sullivan opened for Buddy Guy on his East Coast tour during the summer, played his own set at the popular summer music festival Lollapalooza, as well as the Austin City Limits Festival in October.^{[citation needed]}. In 2011, he appeared on the Jimmy Kimmel Live! show.

William Thomas "Tommy" Emmanuel AM (born 31 May 1955) is an Australian guitarist and occasional singer, best known for his complex fingerstyle technique, energetic performances and the use of percussive effects on the guitar. In the May 2008 and 2010 issues of Guitar Player Magazine, he was named as "Best Acoustic Guitarist" in their readers' poll. In June 2010 Emmanuel was appointed a Member of the Order of Australia (AM).

Emmanuel was born in Australia in 1955. He received his first guitar in 1959 at age four, being taught by his mother to accompany her playing lap steel guitar. At the age of 7 he heard Chet Atkins on the radio. He vividly remembers this moment and says it greatly inspired him.

By the age of 6, in 1961, he was a working professional musician. Recognizing the musical talents of Tommy and his brother Phil, their father created a family band, sold the family home and took his family on the road. With the family living in two station wagons, much of Emmanuel’s childhood was spent touring Australia with his family, playing rhythm guitar, and rarely going to school. The family found it difficult living on the road; they were poor but never hungry, never settling in one place. His father would often drive ahead, organize interviews, advertising and finding the local music shop where they'd have an impromptu concert the next day. Eventually the New South Wales Department of Education insisted that the Emmanuel children needed to go to school regularly.
