Kathy does not name her tours, this was just the name Bravo tagged to this special.
Kathy is not a classic standup who usually has a set slate of jokes. Her show follows daily headlines and gossip and no two shows are the same. And she makes up new bits right up until the moment she takes to the stage. Sure, she will have some material you have seen, but each day her show changes.
In this case Balls of Steel was taped a while ago, so a bunch of the content from it is already not in use.
In short....you never know what Kathy will do on any given night which is what makes her so much fun

take care
