The Sunday Observer newspaper (UK) yesterday published a list of the UK's richest entertainers. Ignoring the rumours, only definite financial information was used, and Jay Kay made it to number 9 in the list with an estimated worth of 15 million pounds. Here's what they said: "Signed to Sony on the strength of one song for an eight-LP deal and a £100,000 advance in 1993, Jason Kay, singer with Jamiroquai, has gone on to sell 10.7 million records worldwide. He receives the lion's share of record royalties, co-writing with only one other member of the band. Jamiroquai has sold two million records in Japan, where records are more expensive, and revenue consequently higher. This money has been sunk into a country house, Horsenden Manor, whose 72 acres are worth ú1.6m, and a fleet of cars whose total value nears £1.5m. In July he turned down a £1.5m deal to appear in a Pepsi advertising campaign."
