Outside of a last minute thing - like I think Chris Rock did a "Tonight I'm running my hour at the Comedy Store - tickets on sale now", but generally it's just a drop in.

For these Chappelle tapings though - he did a run of like 7 nights in the Belly Room and all they did was say "Huge guest, you dont want to miss this - buy tix now" and I had a feeling so I bought them. When I got there, it was all but a certainty. It doesn't say secret for long. I did go the first night though.

If a comic is hosting something - the Emmys, SNL, Oscars, etc. - chances are they'll run material at the Store the week of.
