Comedian who opened for Mitch Hedberg at the Laff Stop around 2004-2005

I was lucky enough to see Mitch Hedberg at the Laff Stop a few months before he passed away. This must have been 2004-2005. Im trying to find info on the show and who the opener was, but my internet sleuthing isnt turning up much. Is there an archive of Laff Stop performers anywhere or anyone I could ask?
