The Napster UK music download service has available for (pay) download the Kraak & Smaak remix of Seven Days In Sunny June - a remix which is not available on any official release of the single.  iTunes (UK) looks like it will be offering a similar download as well - they are displaying a "Jamiroquai Exclusive Remix" link graphic on the iTunes Store homepage although as of earlier today it was linking through to the regular maxi CD single purchase page.
