Michael Kay (footballer)
Michael Joseph Kay (born 9 December 1989 in Consett, England) is an English former footballer.

 He is a former England Under-17 international.
 He is no relation to former Sunderland defender John Kay. Flying shuttle
The flying shuttle was one of the key developments in the industrialization of weaving during the early Industrial Revolution.
 It allowed a single weaver to weave much wider fabrics, and it could be mechanized, allowing for automatic machine looms.
 The flying shuttle was patented by John Kay (1704–c. 1779) in 1733.
 This greatly speeds up the previous hand process, and it halves the labour force.
 Where a broad-cloth loom previously required a weaver on each side, it can now be worked by a single operator.
 Until this point the textile industry has required four spinners to service one weaver.
 Kay's innovation, in wide use by the 1750s, greatly increases this disparity. Wolftracks
Wolftracks is an album by John Kay and Steppenwolf, released in 1982 (see 1982 in music).
 It was originally released only in Canada and Australia.
 The album was the first new studio album in six years for John Kay, with a new line-up of Steppenwolf. Rushton Moreve
Rushton Moreve (born John Rushton Morey; November 6, 1948 – July 1, 1981) was an American bass guitarist best known for his work with the rock band Steppenwolf from 1967–68 and again in 1978.
 According to singer John Kay, Moreve was an intuitive bassist with a melodic style that brought a non-commercial sound to Steppenwolf, a technique exemplified on the hit he co-wrote with Kay, "Magic Carpet Ride". John Kay (spinning frame)
John Kay was a clockmaker from Warrington, Lancashire, England, associated with the scandal surrounding invention of the spinning frame in 1767, an important stage in the development of textile manufacturing in the Industrial Revolution.
 Kay constructed the first known frame, and is one of the claimants to having been its inventor.
 He is sometimes confused with the unrelated John Kay who had invented the flying shuttle thirty years earlier. Peter Kay

 His 2010-11 stand-up comedy tour was officially inaugurated into the "Guinness World Records" as the most successful of all time, playing to over 1.2 million people.
 In a 2004 poll for the BBC, Kay was named the 46th most influential person in British culture. Rise &amp; Shine (Steppenwolf album)
