What horror movie was Southern Culture on the Skids in?

I know they were in one but can't find the title. They may be uncredited. Seriously, don't give me links to imdb or wikipedia or their website. I already looked there. Then I'll forget to pick a best answer and somebody'll get credit for some lame useless answer listing links everybody knows again. Here are there names: Rick Miller, Dave Hartman, Mary Huff. If it helps.
