Bernard Mayes was a staff announcer and reader when I first arrived at KPFA. From his work with BBC, and a luminous speaking and acting voice he led me, with demonstrative advice, on how to perform in radio. It first occurred as we were descending into the depths of Exham Priory, reading from our H.P Lovecraft script. Suddenly Mayes made a quick ad-lib: “Mind that stone !” which I quickly did. Without that warning and departure from the script I would have fallen headlong into the horrendous depths before us.
