I was in rural India for a friend’s wedding. They set up a giant tent pavilion to use as a dining hall, with fans hanging from the top. This was a ways away from the main house, but there were some power lines nearby so they just got power straight from the grid.
Also, day of the wedding, there was a large sound system for the musicians and priest. All the components were plugged into a power strip, which was powered by a couple loose wires stuffed into an outlet
