In the same blog that I found "Mitch Michaels", I found reference to a "Marvelous Mark".
This is a closed blog, as I mentioned in a previous post, so I cannot get any information from the folks maintaining it, nor from the founder, since he's passed away.
Does anyone remember a "Marvelous Mark" from 1977? The date of the aircheck is 11/20/1977.
