p.s. It's great to hear the the ABT now has an open access policy for its archival videos. I think Ananiashvili's retirement SL was recorded, and I'd love to relive the thrill of that night.
Check the catalog listing. I remember seeing some entries that do specifically require written permission before viewing. But I have a stack of print-outs of ABT recordings without that qualifier and that I haven't had trouble viewing.
