Retro Rhythm Review plays a wedding

I am on a wedding gig with Retro Rhythm Review. Peder is on bass. I show up to the gig and we are playing on some weird slanted bleachers, and Peder says I should set up beside him. I say that it will be impossible because my keyboard will just slide down and I can't play at an angle. I point out that the top of the bleachers is flat and I decide to set up there. I go to get my gear. There is a violinist playing in another room. I overhear Neil talking to the bride and saying how amazing the violinist sounds. I continue back to the gig room. The bleachers we are playing on are no longer slanted and they are much larger. As I'm entering the room, some random woman is saying that our sound check is starting now. I have not even started setting up but everyone else in the band is ready to play. I am panicking to get set up. I go to the very top of the bleachers and start setting up but I realize I have left one of my cables at home. I am distressed.
