My 1953 (Vintage Press) Burl Ives paperback songbook includes a list of his LPs at the back. He had a whole series released by Encyclopedia Britannica Films that included discs covering different historical periods. I wanted to try and get his versions of songs from the Revolutionary War era. Do the discs exist, or must we wait until the great MIDI cornucopia of the future gets around to these? Anyone have a clue--any librarians reading this?So many thanks. Pablo
