Ed Sheeran makes a cameo on this Sunday’s episode of The Simpsons. The British singer shows up as Brendan, a musician battling Nelson Muntz for Lisa Simpson’s affections, in “Haw-Haw Land.”In a brief teaser released by Fox, Sheeran is seen playing piano while Lisa plays her saxophone. Homer Simpson, meanwhile, bangs on the wall to get them to bring it down. “Oh no! They’re playing in time to the beat of my banging,” he complains.
