7. There were only five copies of the "Diesel Power" promo single pressed.
The sample from Kool Keith's line from the Ultramagnetic MC's "Give The Drummer Some" on "Smack My Bitch Up" is the more well-known Prodigy/Kool Keith fusion, but they actually had Kool Keith spit lyrics on Fat of the Land album-track "Diesel Power." There's no real word as to why this occurred, but five limited-edition, one-sided 12" acetates were pressed of "Diesel Power." This release went out in January of 1997, about six months before Fat of the Land was released - maybe they were trying to capitalize on the success Keith was having with his Dr. Octagon/Sex Style releases? Who knows. If you're one of those five lucky people to own a copy of this acetate, we can only imagine how you could fetch for it on eBay right now.
