Yes, it absolutely is. It's not even terribly uncommon at rock shows.
Source: I'm a stagehand. I can show you a pay stub from a couple months ago when I worked 20 hours in one day. We were the band's first stop on the tour, so the load-in started at 4am, and the load-out finished at 3am. I had 3 hours off during the show itself, though some people got to work straight through.
I couldn't do it every day, of course, but I'd gladly do it a couple times a week. It was a tremendous experience, and one of my all time favorite days at work.
