Great, I think the podcast really tells the story in a colorful way!

Regarding the merit of one theory over the other: The theory mentioned in the post, where a woman claimed to be Bessie is particularly interesting to me. After the death of this women, they found in her private belongings the marriage certificate of Glen and Bessie. However, people don't believe it is Bessie since when comparing photos they do not look alike.

Regarding the Glen Hyde / Ian McKellen thing: yes, now that you've mentioned it, I can see some resemblance there for sure!
