Passage: In 1975 his orchestral Fourth Sonata (written 1974–75) won the Scottish National Orchestra's Ian Whyte Award. Subsequent orchestral works include the widely performed Night Music (1976), Sonata No. 5: Landscape (1977–81), and a First Cello Concerto, commissioned by the BBC for the 1984 Proms: these last two have been recorded by Unicorn-Kanchana. In 1989 Cortège was given its first performance by the Orchestra of the Royal Opera House under Bernard Haitink, and Quatrain by the London Symphony Orchestra and Michael Tilson Thomas. This was the first of a series of LSO commissions, followed by Machines and Dreams for their 1991 Childhood Festival, Memorial in 1993 with Mstislav Rostropovich as conductor, and a Second Cello Concerto for Rostropovich in 1996. In 1990 he made a setting of three comic poems by Wendy Cope, Strugnell's Haiku. Matthews was Associate Composer with the LSO from 1992 until 1999. The orchestral version of Hidden Variables was a joint commission for the LSO and the New World Symphony Orchestra, who gave the American première in Miami under Michael Tilson Thomas in 1992; in the same year the Cleveland Orchestra gave the American première of Machines and Dreams. Collins Classics released a CD of Matthews' LSO commissions in 1996 to celebrate his 50th birthday.

Passage: Prior to his junior season, McKinney was projected as a first round selection in the 2015 NFL draft. On January 9, 2015, McKinney announced that he had decided to forgo his senior season and enter the 2015 NFL draft. Before the start of the pre-draft events, McKinney was ranked as the second best linebacker in the draft by NFL analyst Mike Mayock. He was one of 34 collegiate linebackers to attend the NFL Scouting Combine in Indianapolis, Indiana. McKinney completed all of the essential combine drills and finished second among all linebackers in the vertical jump, fifth in the broad jump, ninth in the short shuttle, tenth in the 40-yard dash, and tied for 11th amongst his position group in the three-cone drill. On March 4, 2015, he attended Mississippi State's pro day, but opted to stand on his combine numbers and only performed positional drills for the team representatives and scouts from 29 NFL teams, including New York Jets' defensive coordinator Kacy Rodgers and New Orleans Saints' assistant head coach Joe Vitt. As a highly sought after prospect, McKinney attended private visits and workouts with multiple NFL teams, including the Philadelphia Eagles, Dallas Cowboys, San Francisco 49ers, Baltimore Ravens, Miami Dolphins, Carolina Panthers, Cleveland Browns, Denver Broncos, New Orleans Saints, Chicago Bears, and Minnesota Vikings. At the conclusion of the pre-draft process, McKinney was projected to be a second round pick by NFL draft experts and scouts. He was ranked the third best linebacker in the draft by NFL analyst Lance Zierlein, was ranked the fourth best linebacker by Sports Illustrated, was ranked the fifth best inside linebacker by Charles Davis, and was ranked the fifth best linebacker in the draft by NFL analyst Mike Mayock.

Passage: In the 11th century, Errand of Harcourt and his three brothers followed William the Conqueror, duke of Normandy, on the Norman invasion of England, and the brothers were installed with English lands. The English Harcourt branch entered the English peerage, as barons then viscounts then earls. At first the Harcourts had lands in Leicestershire, but in 1191 Robert de Harcourt of Bosworth inherited lands of his father-in-law at Stanton in Oxfordshire, which then became known as Stanton Harcourt. The manor of Stanton Harcourt has remained in the Harcourt family to the present day, although from 1756 to 1948 their main residence was at Nuneham House, also in Oxfordshire. Simon Harcourt was created Baron Harcourt in 1711 and Viscount Harcourt in 1721. The third viscount was created Earl Harcourt in 1749, but all titles were extinguished with the death of marshal William Harcourt, 3rd Earl Harcourt, in 1830. His cousin Edward Vernon, Archbishop of York, thus inherited the majority of that branch's lands and titles and took the name and heraldic shield of the English Harcourt family by royal authorisation on 15 January 1831. This created the Vernon-Harcourt branch, descended from a Harcourt woman. The title Viscount Harcourt was created a second time in 1917 for Lewis Harcourt, but the title was again extinguished on the death of his son.
