It's possible that:
* You might be misremembering the episode number. "Soul Train" ran for many years, and it's easy to get episode numbers mixed up.
* The episode number isn't standard. There might be different numbering systems used by different sources.
* You're referring to a specific performance rather than a full episode. Knowing the specific performance (song, artist, etc.) might help in identifying the episode.
To find the release date, you could try:
* Searching for "Soul Train" episode guides or archives. Many online resources might have information about specific episodes, including air dates.
* Using a search engine like Google. Try searching for "Soul Train" along with the artists or specific songs you remember.
* Consulting a television program guide from the time period. This might have information about the air dates of specific episodes.
Please provide more information about what you remember about the episode (date range, specific songs or artists, etc.) so I can try to help you find the correct release date.
