committed. It was later changed to Homer being hospitalized for wearing a pink shirt, an idea pitched by Brooks. Jackson pitched several story ideas, such as Bart telling everyone in town that Jackson was coming to his house. He also requested a scene in which he and Bart write a song together and asked that a joke about Prince be changed to one about Elvis Presley. According to Jean, Jackson would not commit to the episode until after a read-through of the script. The read-through was held at Jackson's manager Sandy Gallin's house, and Dan Castellaneta (the voice of 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. Lennon recorded his lines at the same time as Jackson, who found the impersonations humorous. Jackson attended the recording session alone and did not use the special trailer set up for him. According to Jean, Jackson did record versions of the singing parts, but Simpsons music editor Chris Ledesma said they were not used. Kompowsky's normal speaking voice, heard at the end of the episode, was recorded by cast member Hank Azaria. The episode originally was supposed to end with Kompowsky singing a portion of Jackson's song "Man in the Mirror", but it was changed to "Happy Birthday Lisa". "Stark Raving Dad" was the final episode in the season two production run, but aired as the premiere of season three on September 19, 1991, over a year after it was completed. Michael Jackson was credited with pseudonym John Jay Smith in the closing credits. At the time, the producers of the show were legally prevented from confirming that Jackson had guest-starred, although many media sources assumed it was really him. Similarly, in season two, actor Dustin Hoffman had guest-starred in the episode "Lisa's Substitute" under the name "Sam Etic". After "Stark Raving Dad", the producers decided that guest stars would have to agree to be credited. Jackson was a fan of Bart, and wanted to give Bart a number one single. He co-wrote the song "Do the Bartman", which was released as a single
