Mark McKeever (born 16 November 1978, Derry, Northern Ireland) is a former professional and semi-professional football player who last played for Conference South club Weston-super-Mare.

McKeever began his football career with Norwich City as a youth team player. He was eventually released and moved on to Peterborough United with ex-Canaries coach Kit Carson. McKeever became a trainee with the club, but after only 3 appearances he was transferred to Sheffield Wednesday in April 1997 with David Billington for £1,000,000.

McKeever made three appearances in the Premier League and was looking to break into the first team before a foot injury prematurely ended his season. He was subsequently sent on loan to Bristol Rovers and later Reading. During his stint with the Royals he looked like George Best in a 4-0 away victory over Stoke City. However, over the following weeks, Stoke full-back Jason Kavanagh made a full catalogue of Division Two wingers look like Best at his peak.

McKeever made his 6th appearance for Wednesday in an FA Cup tie against Bristol City in December 1999. A year later, Mark was linked with a return to Bristol Rovers after Rovers had supposedly tabled a £100,000 bid for him. But the permanent move did not materialise.

Francesco degli Organi, Francesco il Cieco, or Francesco da Firenze, called by later generations Francesco Landini or Landino (ca. 1325 or 1335 – September 2, 1397) was an Italian composer, organist, singer, poet and instrument maker. He was one of the most famous and revered composers of the second half of the 14th century, and by far the most famous composer in Italy.

Details of his life are sketchy and few facts can be established with certainty, but the general outline has begun to take shape as more research has been done, especially into Florentine records. Most of the original biographical data on Landini comes from a 1385 book on famous Florentine citizens by chronicler Filippo Villani, who was also born approximately 1325.

Landini was most likely born in Florence, though his great-nephew, humanist Cristoforo Landino, gave his birthplace as Fiesole. His father, Jacopo del Casentino, was a noted painter in the school of Giotto. Blind from childhood (an effect of contracting smallpox), Landini became devoted to music early in life, and mastered many instruments, including the lute, as well as the art of singing, writing poetry, and composition. Villani, in his chronicle, also stated that Landini was an inventor of instruments, including a stringed instrument called the 'syrena syrenarum', that combined features of the lute and psaltery, and it is believed to be the ancestor of the bandura.

Guillaume Dufay (Du Fay, Du Fayt) (August 5, 1397? – November 27, 1474) was a Franco-Flemish composer of the early Renaissance. As the central figure in the Burgundian School, he was the most famous and influential composer in Europe in the mid-15th century.

From the evidence of his will, he was probably born in Beersel, in the vicinity of Brussels. Circumstantial evidence claims him to have been born the illegitimate child of an unknown priest and a woman named Marie Du Fayt, though this suggestion is as of yet unproven. Marie moved with her son to Cambrai early in his life, staying with a relative who was a canon of the cathedral there. Soon Dufay's musical gifts were noticed by the cathedral authorities, who evidently gave him a thorough training in music; he studied with Rogier de Hesdin during the summer of 1409, and he was listed as a choirboy in the cathedral from 1409 to 1412. During those years he studied with Nicolas Malin, and the authorities must have been impressed with the boy's gifts because they gave him his own copy of Villedieu’s Doctrinale in 1411, a highly unusual event for one so young. In June 1414, at the age of only 16, he had already been given a benefice as chaplain at St. Géry, immediately adjacent to Cambrai. Later that year he probably went to the Council of Konstanz, staying possibly until 1418, at which time he returned to Cambrai.
