Ivan Vaughan (18 June 1942 - 16 August 1993) was a boyhood friend of John Lennon, and later schoolmate of Paul McCartney at the Liverpool Institute, both commencing school there in Sept. 1953. He was born on the same day as Paul McCartney in Liverpool. He played bass part-time in Lennon's first band, The Quarrymen, and was responsible for introducing Lennon to Paul McCartney at a community event (the Woolton village fête) on July 6, 1957, where The Quarrymen were performing. McCartney impressed Lennon, who invited McCartney to join the band, which he did a day later. This led to the formation of Lennon and McCartney's songwriting partnership, and later of The Beatles.

Vaughan studied classics at University College, London, married in 1966 and settled down to family life with a son and daughter, and became a teacher.

Lennon and McCartney never forgot the friend who brought them together. For a time they put Vaughan on the payroll of their Apple company, in charge of a plan that never took off to set up a school with a Sixties, hippie-style education ethos. Vaughan's wife Jan, a languages teacher, was hired to sit down with Lennon and McCartney and help with the French lyrics to the 1965 song "Michelle".

Vaughan ( /ˈvɔːn/ VAWN; 2011 population 288,301) is a city in York Region north of Toronto, Ontario, Canada. Vaughan was the fastest-growing municipality in Canada between 1996–2006, achieving a population growth rate of 80.2% according to Statistics Canada having nearly doubled in population since 1991. Vaughan is located in Southern Ontario and is part of the Greater Toronto Area.

In the late pre-contact period, the Huron-Wendat people populated what is today Vaughan. The Skandatut ancestral Huron village overlooked the east branch of the Humber River (Pinevalley Drive), and was once home to approximately 2000 Huron in the sixteenth century. The site is located close to a Huron ossuary (mass grave) uncovered in Kleinburg in 1970, and one kilometre north of the Seed-Barker Huron site

The first European to pass through Vaughan was the French explorer Étienne Brûlé, who traversed the Humber Trail in 1615. However, it was not until the townships were created in 1792 that Vaughan began to see any settlements, as it was considered to be extremely remote and the lack of roads through the region made travel difficult. The township was named after Benjamin Vaughan, a British commissioner who signed a peace treaty with the United States in 1783.

John Winston Ono Lennon, MBE (9 October 1940 – 8 December 1980) was an English musician and singer-songwriter who rose to worldwide fame as one of the founder members of The Beatles, one of the most commercially successful and critically acclaimed acts in the history of popular music. Together with Paul McCartney, he formed one of the most celebrated songwriting partnerships of the 20th century.

Born and raised in Liverpool, Lennon became involved as a teenager in the skiffle craze; his first band, The Quarrymen, evolved into The Beatles in 1960. As the group disintegrated towards the end of the decade, Lennon embarked on a solo career that produced the critically acclaimed albums John Lennon/Plastic Ono Band and Imagine, and iconic songs such as "Give Peace a Chance" and "Imagine". After his marriage to Yoko Ono in 1969, he changed his name to John Ono Lennon. Lennon disengaged himself from the music business in 1975 to devote time to raising his infant son Sean, but re-emerged with Ono in 1980 with the new album Double Fantasy. He was murdered three weeks after its release.

Sir James Paul McCartney, MBE, Hon RAM, FRCM (born 18 June 1942) is an English musician, singer-songwriter and composer. Formerly of the Beatles (1960–1970) and Wings (1971–1981), he has been described by Guinness World Records as "The Most Successful Composer and Recording Artist of All Time", with 60 gold discs and sales of over 100 million albums and 100 million singles. With John Lennon, George Harrison, and Ringo Starr, he gained worldwide fame as a member of the Beatles, and with Lennon formed one of the most celebrated songwriting partnerships of the 20th century. After leaving the Beatles, he began a solo career and later formed the band Wings with his first wife, Linda Eastman, and singer-songwriter Denny Laine.

According to the BBC, his Beatles song "Yesterday" has been covered by over 2,200 artists—more than any other song. Wings' 1977 release, "Mull of Kintyre", became one of the best-selling singles ever in the UK, and he is "the most successful songwriter" in UK chart history, according to Guinness. As a songwriter or co-writer, he is included on thirty-one number one titles on the Billboard Hot 100, and as of 2012 he has sold over 15.5 million RIAA certified units in the United States.

Stephen Ray "Stevie" Vaughan (October 3, 1954 – August 27, 1990) was an American guitarist, vocalist, songwriter, and a notable recording artist. Often referred to by his initials, SRV, he is best known as the leader of the blues rock band Double Trouble, with whom he recorded four studio albums. Influenced by guitarists of various genres, Vaughan emphasized intensity and emotion in his guitar playing, and favored vintage guitars and amplifiers. He became one of the leading blues rock musicians, encompassing multiple styles, including jazz and ballads.

Born and raised in Dallas as the younger brother of Jimmie Vaughan, he moved to Austin at the age of 17, and formed the band, Triple Threat Revue, that evolved into a band called Double Trouble, in 1978. Accompanied by drummer Chris Layton, bassist Tommy Shannon, and later, keyboardist Reese Wynans, Vaughan became an important figure in Texas blues, a loud, swing-driven fusion of blues and rock. Despite the breakthrough success of Double Trouble's debut Epic album, Texas Flood (1983), Vaughan entered a period of alcohol and drug addiction. In 1986, he successfully completed rehabilitation and released the album In Step in (1989). On August 27, 1990, while departing a concert venue by helicopter in East Troy, Wisconsin, Vaughan was killed when the helicopter crashed into the side of a ski hill. His death triggered a global outpouring of grief, and as many as 3,000 people reportedly attended his public memorial service in Dallas.
