The Japanese release of Rock Dust Light Star includes a track called 'That's Not The Funk I Want' as a bonus track.  Thanks to the good people at jamirotalk.net who found this, you can legally download the track for free by registering at jamiroquai.de and then using a code you get emailed to 'pay' for the track at saturn.de.

It's not too confusing (even if you don't understand a word of German) and you should get the link to the MP3.
