Just listened to the Nothing Is Real Beatles podcast featuring a two-part interview with Mark Lewisohn. Really worth a listener Beatles nerds. One fascinating snippet for me was that Mark was asked whether he was planning to create an archive of his research material. He said he was but hadn’t got round to it yet (right answer as he should be concentrating on finishing Vol 2 of All My Years before I pop my clogs!). He had, however, moved his office and the archive weighed over 13.2 tons! That’s an incredible amount of material, and he said he doesn’t really collect artefacts or obvious memorabilia, just loads and loads of information. Difficult to imagine what other band could come even close to such a mountain of material.
