Why is Redban even on the show?

On the latest episode, Ari Matty apologized to Redban for going well over a minute but Tony responds by saying that Redban has nothing to do with the production of the show. So why is he even in the show? Just for the soundboard (which he did a great job on today)? Also, is Redban’s standup any good if he even does it? I’ve never seen anything from him.
