A very easy to install group of 3 extra backgrounds can be found here:
positech.co.uk/rocklegend/mo … sPack1.exe
and there are other mods here:

Cheers!
awesome, thanks Cliff 
So I downloaded them both, I even had to download a program that my comp will use to open .rar files. When I try to use the game, I can’t get any of the backgrounds at all. I am like mega retarded when it comes to modding the game, so what exactly do I have to do?
Copy paste all of the backgrounds into the files of the game?
What happens when I search for the skins is that the WinRaR program opens & I can see the files but then I am stuck there wondering what to do. HELP! I love how cool they look but what can I do???
