Sir John "Black Jack" McEwen, GCMG, CH (29 March 1900 – 20 November 1980), was an Australian politician and the 18th Prime Minister of Australia. He is the last member of the Country Party to serve as prime minister.

McEwen's stern demeanour earned him the nickname "Black Jack" (Sir Robert Menzies called him "Le Noir").

McEwen was born at Chiltern, Victoria, where his father was a pharmacist. He was educated at state schools and at 15 became a junior public service clerk. He enlisted in the Army immediately upon turning 18 but the First World War ended while he was still in training. He commenced dairy farming at Stanhope, Victoria, near Shepparton.

McEwen was active in farmer organisations and in the Country Party. In 1934 he was elected to the House of Representatives for the electorate of Echuca, switching to Indi in 1937 and Murray in 1949. Between 1937 and 1941 he was successively Minister for the Interior, Minister for External Affairs and simultaneously Minister for Air and Minister for Civil Aviation. In 1940 when Archie Cameron resigned as Country Party leader he contested the leadership ballot against Sir Earle Page: the ballot was tied and Arthur Fadden was chosen as a compromise.

Sir John Blackwood McEwen (13 April 1868 – 14 June 1948) was a Scottish classical composer and educator.

John Blackwood McEwen was born in Hawick in 1868. After initial training in Glasgow, he studied with Ebenezer Prout, Corder and Tobias Matthay at the Royal Academy of Music in London. After returning to Scotland, where he was a choirmaster and teacher at Greenock and Glasgow, he was invited to become Professor of Harmony and Composition at the RAM, from 1898 until 1924, and was Principal between 1924 and 1936.

With Frederick Corder and Tobias Matthay, McEwen co-founded the Society of British Composers in 1905, and also served as president of Incorporated Society of Musicians.

He was knighted in 1931 and died in 1948 in London, aged 80.

He is best known for orchestral works on his native Galloway, such as A Solway Symphony (1909), Hills o' Heather and Where the Wild Thyme Blows (1918). His Three Border Ballads include "Grey Galloway" (1908), "The Demon Lover" (1906–1907) and "Coronach" (1906). Other works include Hymn on the Morning of Christ's Nativity, a setting of The Hymn from Milton's Ode of the same title. He wrote a Viola Concerto in 1901 at the request of Lionel Tertis, and nineteen string quartets (only seventeen are numbered), written over a fifty-year period (1893–1947).

John Blackwood FRSE (1818–1879) was a Scottish publisher, younger brother of William Blackwood. John succeeded his brother as head of the business in 1834, on William's death; four years later he was joined by Major William Blackwood, who continued in the firm until his death in 1861. In 1862 the major's elder son, William Blackwood (born 1836), was taken into partnership. John Blackwood was a man of strong personality and great business discernment; it was in the pages of his magazine that George Eliot's first stories, Scenes of Clerical Life, appeared. He also inaugurated the "Ancient Classics for English readers" series, to which William Lucas Collins contributed.

The Blackwood family still live to this day in Ayrshire, Scotland around the Doon Valley Area and Other parts of Ayrshire.

John B (born John Bryn Williams, 1977, Maidenhead, Berkshire, England) is an English DJ and electronic music producer. He is widely recognised for his eccentric clothing and wild hair and his production of several cutting edge drum and bass tracks.

John B ranked #76 in DJ Magazine 's 2010 Top 100 DJs annual poll, announced on 27 October 2010.

Williams started producing music around the age of 14, and now is the head of drum and bass record label Beta Recordings, together with its more specialist drum and bass sub-labels Nu Electro, Tangent, and Chihuahua. He also has releases on Formation Records, Metalheadz and Planet Mu.

Williams was ranked 1st drum and bass DJ on the 2009 DJMag's top 100. and #92 on the DJ List as of October 3, 2009.

He attended Durham University.

While his trademark sound has evolved through the years, it generally involves female vocals and trance-like synths (a style which has been dubbed "trance and bass", "trancestep" and "futurestep" by listeners). His most recent concentration is an 1980s electroclash influenced fusion of electro and drum and bass, which was dubbed 'electrostep'. At first (around early 2002), this style seemed odd and comical to some in the drum and bass community. However, this move has given John the ability to carry his style of drum and bass forward. He has dabbled in darkstep, jazzstep and various other styles in his time. When he DJs, he is known to spin both drum and bass and electrohouse, sometimes with other genres such as disco and rock, in the same sets.
