BBC Radio Dramatization  - first book of the trilogy "Lord of the Rings" written by JRR Tolkien  - "The Fellowship of the Ring"

The 26-part series was subsequently edited into 13 hour-long episodes, restoring some dialogue originally cut for timing (since each hour-long episode is actually around 57 minutes, as opposed to 54 minutes for two half-hour episodes), rearranging some scenes for dramatic impact and adding linking narration and music cues.
