WogBlog has an excellent post today detailing the many contributions Beatles fan and official archivist has made to the band's post-breakup projects: From the Rarities compilation, through the First U.S. Visit documentary, Anthology and much more.
Furmanek also helped roundup footage for the great 1974 short film "Braverman's Condensed Beatles." I saw it in a social studies class in school once and was entranced. It's like watching the Anthology series in seven minutes. You really see how much the band changed in seven years.
