According to Jean, Jackson would not commit to the episode until after a read-through of the script. The read was held at Jackson's manager Sandy Gallin's house, and Dan Castellaneta (who provides the voice for Homer) was 30 minutes late. Jean recalls that "no one said a word, we just sat there waiting". Following the read, Jackson stipulated his conditions: he would go uncredited, and his singing voice would be performed by a soundalike. Leon Kompowsky's singing parts were performed by Kipp Lennon, because Jackson wanted to play a joke on his brothers and fool them into thinking the impersonator was him.
