It's possible that:
* The name is misspelled. Perhaps the name is slightly different, or the production is spelled differently.
* The production is obscure. It could be a regional or amateur production that is not widely known.
* There is a misunderstanding. It's possible you're thinking of a different production or actress.
To help me find the information you're looking for, could you please clarify:
* Is "Bus-tin Loose" the correct name of the production?
* Are you sure the actress's name is Janet Wong?
* Do you have any other details about the production, such as the year it was performed or the location?
With more information, I might be able to track down the actress you're looking for.
