In searching for information about Pennie, I came upon the fact that Pennie's name was credited on 2 Grateful Dead albums. She was a member of a group called "The Tailors". I didn't know whether that meant she was a costume designer or a back-up singer or ?  But once I found the attached obituary, I think she probably was connected with the Grateful Dead group as a seamstress. Just a guess tho.
