The only version of the Emergency On Planet Earth album that I've seen has a plain white cover with the buffalo man logo on the front. Well, that was until now. In Japan there was/is a version of the album with the cover sleeve being the drawing of Jamiroquai which is on the liner notes of the album. If you want to have a look, here are the front and back covers of the case (images no longer available).
Travelling Without Moving was at number two in the UK album charts this week in 1996. Supersonic, the second single to be taken from Synkronized, was released this week in the UK in 1999. A Funk Odyssey was at number one this week in 2001.
