I believe this show was sponsored by Mobile Fuel Company. They called it The Mobile Showcase. "When Havoc Struck" was like "In Search Of..." (Leonard Nimoy), hosted by Glenn Ford, a 30 minute program about world disasters. I remember the opening having the "O" in Mobile with filled with gasoline swishing back and forth. Some of the programs were kind of depressing to me but, I watched them anyway. I was about 13 years old. One of the shows I remember well was about the Coconut Grove nightclub fire in Boston. What a sad incident it was. I wonder where these films got to? I'd like to see it again on TV. Does anyone have any information this program?
