Store Hadji, Congratulations on an excellent collection of Welles links.
Here's one that seems to have been overlooked:
1937 Shakespeare Festival. August 30, 1937. Final program of 8. CBS net. "Twelfth Night". Sustaining. Tallulah Bankhead, Cedric Hardwicke, Orson Welles, Mark Smith, Estelle Winwood, Robert Strauss, Helen Menken, Burford Hampden, John Griggs, Ray Collins, Niles Welch, Sydney Smith, Conway Tearle (narrator), Victor Bey (arranger, conductor), William Shakespeare (author), Brewster Morgan (adaptor, producer). Length: 59:31. Filesize: 47.7Mb.
I don't think mediafire is reliable for long-term storage, so this should probably be moved to a more permanent host.
