Also, I should add that I know these particular recordings have not been re-recorded in recent years, so they wouldn't be on CDRs or mp3s previously distributed by Mike Loughlin. Merritt Malvern may have transferred them to 1/4-inch tape in the 1970s. In this case, you might try contacting Larry Tedder, who bought Malvern's tapes. He may be in a position to make duplicate copies more quickly than ENHS. Contact me off-list for details.
