10 Greatest Musician Cameos On The Simpsons
2. Paul and Linda McCartney
Not only did the McCartneys make one of the most prominent musician guest appearances in The Simpsons, but they helped to steer its path going forward. The season seven episode “Lisa The Vegetarian” sees the middle Simpson child give up meat after meeting a particularly sweet lamb at a petting zoo.
Springfield being how it is, the unrefined citizens find her decision entirely baffling. Lisa believes she’ll never meet likeminded individuals - until Apu leads her up to the roof of the Kwik-E-Mart, where she’s introduced to his old friends Paul and Linda McCartney.
While the appearance isn’t as packed with jokes as some other celebrity cameos, the McCartneys add kudos and heft to an episode with a heartfelt message. Paul’s willingness to appear on the show hinged upon the writers’ willingness to maintain Lisa’s vegetarianism going forward, and to complete the set of surviving Beatles, this was a small price to pay.
