Can someone explain this Balcony Stage theme?

I found these three pictures of the Balcony Stage at Northridge in a Reddit post and I was wondering what this theme was. I can see the background says “Working for a Living,” but that showtape wasn’t released until 1992. I do know that Northridge had their Balcony Stage until 1993, so this could be why that theme is present, but the Pizza Time Theatre branding is still present in these photos.

There was another Working showtape released in 1987 which is what this theme was for.

Thanks! I figured as much, but just wanted to be sure.
