I also have a bunch of photos from the first Racer X lineup, courtesy of some guy named racerxfan1. They were in my Racer X folder under "super rare", but I'm sure a lot of these should look familiar.

Talks about the early days at MI. I have no idea what the first two songs are. Street Lethal starts at 33:45. Wasn't kidding about them playing it faster!
