The Lord of the Rings (1979 radio series)
From Tolkien Gateway
The Lord of the Rings was a 1979 radio adaptation by Bernard Mayes, produced by The Mind's Eye.
It is an abridged version of the story, voiced by local Virginia theatre actors, who show serious problems pronouncing the names correctly. Due to a low budget, effects were home made, and music was low-key.
The production was overshadowed by that of the BBC, and is usually considered inferior in quality, music and acting.
