Query: Important Distinguishing Fact

M. Gilkey, in the 2004 review, made a great observation. There are two PBS rock and roll histories. The initial one, "Rock and Roll" was aired circa 1995. I haven't seen "The History of Rock and Roll", which is for sale here. "Rock and Roll" was amazingly well done. It was more or less an academic documentary, not the ratings-grabber of VH-1 years later. The Experience Project of "Rock and Roll" is the way to go. If anyone on here knows how to obtain the original PBS "Rock and Roll", please post. You would be doing a great many people an awesome service.
