[Q]: Question: On what album was the Gerry Rafferty song from that is referenced in the show? Passage:While telling Bart and Lisa about 1990, Homer says, "Tracey Ullman was entertaining America with [...] crudely drawn filler material." This is a reference to The Simpsonss debut as "bumpers" airing before and after commercials on The Tracey Ullman Show. The song "Those Were the Days" parodies the opening credits of the television show All in the Family. One of the people who run over the saxophone is a man on a tricycle, who promptly falls over. This is a reference to the show Rowan & Martin's Laugh-In. At the beginning of the flashback, the song "Don't Worry, Be Happy" by Bobby McFerrin can be heard. In the flashback, Dr. Hibbert fashioned his hair and attire like Mr. T in The A-Team. Homer can be seen watching Twin Peaks and The Giant is then shown waltzing with the White Horse. In King Toot's music store, when Homer buys Lisa her first saxophone, there is a guitar in the background that is similar to Eddie Van Halen's "Frankenstrat" guitar. The photo beside Kent Brockman on the news has him modeled after the Coppertone Girl. At the end of the episode, Lisa performs a brief, cruder rendition of the hook of "Baker Street" by Gerry Rafferty on her new saxophone before the music segues into the original song.
