This is off the blog's topic, but I'm bringing it up here because I'm not having much luck finding any info elsewhere.
When I was a kid in the mid-'70s, my school system had these 78s called "Mike-ing History." They were on colored (red or green) vinyl, and featured short newscast-style dramatizations of historical events (like "You Are There"). I took them out and taped them, but shortly afterward they disappeared, and I haven't yet found any more info about them, even on the Web.
If anyone reading this entry has any info about the "Mike-ing History" 78s (or knows where I can find info), please contact me. Thanks.
