opening theme on Youtube

It seems that most of us at this board have in common that we recall very clearly the opening theme but not the name of the show. I have never forgotten that rollercoaster and the eerie whistling. I always thought that it was from The Outer Limits and I have been asking over there to no avail until today and to hear that it was on YOUTUBE was even better!!

I was a kid in 1968 and I dont recall any of the episodes that people have mentioned here but will never forget that opening theme. Either my parents didnt let me watch it or I was too scared too. Having easy going parents, I would say that i was way too scared to watch it.

Anyway enjoy the video clip on YOUTUBE!!
