I know the question is stupid probably because so basic but what means AUDIBLE on a setlist ....
I am asking that because the setlist from the lima show shows HAVE A NICE DAY in the setlist but also as an audible ..so I am confused ... maybe I don't understand what is an audible after so many years ....

I thought an audible was a song that have been put aside as possible to perform that night and used for a change or for an added song ... but is it possible an audible is part of the programmed setlist ?
