Q: Question: What station originally aired the show that "Those Were the Days" parodies the opening credits of? Passage 1:Roberts played youth football for Cessnock before joining APIA Leichhardt in the New South Wales State League. He played at APIA in 1964 and 1965. In 1966, he travelled to England to trial with Football League Division One team Chelsea. After the unsuccessful trial he was signed by Blackburn Rovers in April 1966. Roberts played three times for Blackburn in the 1965–66 season, returning then to APIA where he played the remainder of the 1966 season. He was sent out on loan in August 1967 to Chesterfield in the Football League Fourth Division, where he played 46 matches during the 1967–1968 season. In 1968, he was signed by Bradford City; there he made 44 appearances between 1968 and 1970, and played in the team that won promotion from the Fourth Division to the Third Division in 1969. In early 1971 he transferred to Southend United, and at the end of the 1971–1972 season moved to Northampton Town, staying there for one season and playing 13 times.
 Passage 2:The first domestic title PAOK won, was the 1971–72 Greek Cup. PAOK eliminated Pierikos, Aias Salamina, local rivals Aris in the quarter-finals with a 2–1 victory at Kleanthis Vikelidis Stadium and progressed to the final with their semi-final victory over Lamia. This time PAOK would face league champions Panathinaikos who also reached the 1971 European Cup Final. The final was played once again in Athens at Georgios Karaiskakis Stadium. PAOK players had 10,000 fans on their side and they vowed that it was about time to return with the trophy at Thessaloniki. It was the sixth final for the Double-Headed Eagle of the North and the fifth time that they traveled to Athens for the trophy match. PAOK won the game 2–1 with Koudas scoring both goals. In the second half, a magnificent bicycle kick of Matzourakis found the net, but the goal was surprisingly disallowed by referee Michas. PAOK triumph and 1st Greek Cup title was widely celebrated by the fans at Thessaloniki.
 Passage 3: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.
