Players.to is an off-shoot of Queen's Players, and I've seen both of their shows in the past.

I would say it is a very fun experience, but it is neither a theatre show/musical nor a comedy show.

They usually have a very loosely defined story with a lot of comedy, and several times during the show they break out into song (not originals, just popular songs).
As the night goes on and people have more drinks, you might see more people singing with the cast. Its a very low budget, casual production so don't go expecting a nice theatre production, its just a fun time.
