What you could try is finding a track somewhat similar in shape and length (perhaps the fictional Levi Stratus) and grabbing the cam file from that and renaming it so it that it'll work for Nazareth. I know it's not the best way, but I've done that with plenty of tracks and have gotten some really nice camera views.
I would be interested in any cam files that anyone has. The only ones I have are the ones from NNRacing. I know Masgrafx made a bunch of them back in the day.
