Input: Consider Input: 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.

Input: Consider Input: Question: Was the Rye House Plot successful? Passage:In 1658 Hungerford was elected Member of Parliament for Chippenham in the Third Protectorate Parliament. He was elected MP for Chippenham in 1660 for the Convention Parliament. He was made a Knight of the Bath at the coronation of King Charles II on 23 April 1661. In 1661 he was elected for Chippenham again in the Cavalier Parliament but the election was declared void. He was then re-elected in the by-election later in 1661 and also in the two elections in 1679. In January 1680 he presented a petition for the summoning of a parliament, and his avowed opposition to the court party of King Charles II led to his removal as Lord Lieutenant of his county in May 1681. He settled in Spring Gardens, Whitehall, in 1681 and was elected MP for Chippenham again in the Oxford Parliament of 1681. He was implicated in the 1683 Rye House Plot and his home at Farleigh Castle was searched for arms. He was elected MP for New Shoreham in 1685, 1688, and 1690, and for Steyning in 1695, 1698, 1700, and 1702.
