Jamiroquai are part of the online auction for the T.J Martell foundation. They pitched in by contributing a signed vinyl and signed cd booklet. The auction ends in early May. All the details can be found by following this link.
Around this time in May 2000, bidding on the Mini website for a Jamiroquai customised Mini car finished with the winner driving away in a bit of mini-jamiro-history for just over 14,000 pounds (UK).
