Just found this from Peta Webb on the Musical Traditions site which suggests that there may now be a question mark over either the award posthumously of the badge or of the launch of the book taking place on 13th May (not clear which):
"Frank was due to be awarded the EFDSS Gold Badge at the Beyond Marrow Bones event on Sunday 13th May, to coincide with the launch of the new edition of his book Marrow Bones. It is not now certain whether this event will take place. We will keep you informed. "
