And that tune is precisely why I loved Rush Hour in ONR2. I would practically die with nostalgia if that Chicken Run tune played during rush hour in CSD!
EDIT: Just noticed the OP, lol. I can confirm personally that I know there were two different versions of ONR2 with different music. I'm fairly sure the original had the Chicken Run tune as well as more jazzy type stuff for the main music, while the updated version had the rock tunes. I'm afraid I won't be much help as to where to get which version, but I have definitely played two different versions of ONR2 that had different soundtracks.
EDIT 2: FOUND IT!! - Link appears to still be valid. I confirmed that it has the rock music. Clearly someone
knows how to edit and recompile GMK's...and thought they had better musical taste than Mr. Chubigans!http://www.free-windows-games.com/orenoryomi2.exe
