I think you are on about the Gladiator Remix that Judge Jules was playing a lot. If this is the case then you wont be able to find it as it was stopped from being released. I emailed Jules and Serious Records and apparently they were denied permission to clear the sample. Shame really.
Only other trancey mix of a gladiator nature i can think of is 'Waveburner - Where Spirits Run'. Its ok i suppose. Hope all this helps.
