We recently came across an old newsletter, the Talking Book Topics from January-February 1999, highlighting the then-recent books that were read to cassette and/or CD for the blind and physically handicapped. We were surprised to see three books of John's were listed in the mix:
- The Doom of the Haunted Opera, read by Erik Sandvold.
- The Drum, the Doll, and the Zombie, read by Erik Sandvold
- The Secret of the Underground Room, read by Christopher Hurt.
