It is possible:
* The name is slightly incorrect: There might be a spelling error in the title or the name "Gene London." Perhaps you are thinking of a different show or a different performer.
* The show was a regional or local production: It might be a show that was not widely known or broadcast nationally.
* The show was never formally documented: Some shows, especially those with limited runs or regional productions, may not have been documented in official archives.
Could you provide more information about the show? For example:
* What genre was the show? (e.g., musical, comedy, drama)
* Where was the show staged? (e.g., Broadway, London, regional theater)
* What was the plot or theme of the show?
With more details, I might be able to help you find the information you're looking for.
