I don't have the answer. Anyway, the bass line of the studio version of "Space Cowboy" is one of my all time favorite bass lines. And I've read that it was not played by Stuart.
It's a shame that Stuart hasn't done anything memorable since he left Jamiroquai. Jay + Stu + Toby created magical music together.
