Although not officially confirmed, it appears that Nick Fyffe's replacement and new Jamiroquai bassist is called Alex Meadows. Apparently he has worked with Rob Harris in the past (note also Beverley Knight's drummer, Carlos Hercules, being a member of the same group).
Today in 2001, Jamiroquai recorded amazing live versions of You Give Me Something, Main Vein, Love Foolosophy and Cosmic Girl for the Jools Holland TV show in the UK.
