Jay Kay (born Jason Luís Cheetham; 30 December 1969) is an English singer and songwriter, best known as the lead singer of the acid jazz band Jamiroquai.
Kay was born in Stretford, Greater Manchester, on 30 December 1969. His mother, Karen Kay, is a former cabaret singer and television personality. His biological father is Luís Saraiva, a Portuguese former guitarist, whom he did not meet until 2001. Kay's identical twin, David, died some weeks after they were born. Kay's mother raised him largely alone, which gave him "an itinerant childhood; half of it living in rural Suffolk and rural Devon", according to his 2010 Daily Telegraph interview and his 1990s television interviews. He is also a former resident of Ealing, where he lived on Grange Road (W5) and played some of his first gigs in The Haven, a pub on Spring Bridge Road (now converted to offices) and Broadway Boulevard (now Club Karma). He attended Twyford Church of England High School in Acton.
