beer truck heading for New Springfield and dumps its contents in the river; Homer and New Springfield then cut off their water supply. When the lack of water reveals gold in the river bed, making Old Springfield even richer and allowing the town to purchase a French water factory, an enraged Homer has a wall built between the two towns. However, a lack of supplies and sanitation drives all of the New Springfield residents over to Old Springfield, leaving the Simpsons alone. Bitter, Homer attempts to sabotage the Who concert in Old Springfield by convincing them to play in New Springfield instead. When the people of Old Springfield realize this, they confront the Simpsons at the wall. After a brief riot during which flaming garbage is catapulted into New Springfield, the members of the Who hear about the area code problem and suggest that the townspeople get speed dial. Pete Townshend's opening riff from "Won't Get Fooled Again" crumbles the wall, and the citizens of Springfield reunite and dance to the music as the badger leads an animal invasion of the town. Production The episode was pitched by John Frink and Don Payne. The episode was inspired by Don Payne's mother's neighborhood, where one side would spread rumors about the other side. Larry Doyle then pitched that the sides split apart because of different area codes. During production the staff did not want one side to be slobs like Homer Simpson and the other snobs like Mr. Burns, but this ended up happening in the final product. The writers later created a website about what badgers eat. The phone from the educational cartoon was voiced by Dan Castellaneta. Pete Townshend did not guest star in the episode as he did not know he would be providing his own voice and assumed someone else would, as in Yellow Submarine. Roger Daltrey, John Entwistle and Pete's brother Paul Townshend provided guest voices in the episode. After a number of calls were made by the show's casting director in Los Angeles to the Who's managers in London, the group agreed to appear on the show. The Who recorded their lines in England, but weighed in on script details. During the production the staff decided to animate Keith Moon in honor of him since he died in 1978 instead of the Who's current drummer Zak Starkey. Deleted scenes When Roger Daltrey hits Marge with
