My brother-in-law just dubbed off a very clean copy of the 1938 radio show and on the end of it is a segment of WKBW's version from 1969. What I heard sounded very much like a Top 40 station in "news mode". It sounded pretty realistic, based on what you would expect to hear on the radio at the time and having the martians attacking in downtown Buffalo was a nice touch. I understand they received about 4000 phone calls and made the newspapers all over the country! Of the 1938 version: Orson Welles was interviewed about 30 years later and said that despite the initial short-lived panic, most people didn't believe it and in fact, thought it was funny! That's the first time I've ever heard anyone say that the believers were in the minority.
