Sweeney Todd Cancellation Line

I’m surprised this isn’t a thread yet, unless the search engine has become even worse lately. How is the cancellation line for Sweeney? Do people queue at a certain time? Are there generally a couple tickets released each night this way? I’m aware of the lotto and SRO, but I’m thinking cancellation line might be my best shot.

What time do people line up?
