Question: How close is Wrigley Field to the source of drinking water for the city that a prominent adult contemporary band from this period, along with the Eagles and the performer of Son of Your Father, was named after?

<P0-S0> The water cribs in Chicago are structures built to house and protect offshore water intakes used to supply the City of Chicago with drinking water from Lake Michigan. <P0-S1> Water is collected and transported through tunnels located close to 200 feet beneath the lake, varying in shape from circular to oval, and ranging in diameter from 10 to 20 feet. <P0-S2> The tunnels lead from the cribs to one of two water purification plants located onshore, the Jardine Water Purification Plant (the world's largest) and the Eugene Sawyer Water Purification Plant, where the water is then treated before being pumped to all parts of the city as well as 118 suburbs. <SEP> <P1-S0> In April and May the wind often comes off Lake Michigan (less than a mile to the east), which means a northeast wind ``blowing in ''to knock down potential home runs and turn them into outs. <P1-S1> In the summer, however, or on any warm and breezy day, the wind often comes from the south and the southwest, which means the wind is`` blowing out'' and has the potential to turn normally harmless fly balls into home runs. <P1-S2> A third variety is the cross-wind, which typically runs from the left field corner to the right field corner and causes all sorts of havoc. <P1-S3> Depending on the direction of the wind, Wrigley can either be one of the friendliest parks in the major leagues for pitchers or among the worst. <P1-S4> This makes Wrigley one of the most unpredictable parks in the Major Leagues. <SEP> <P2-S0> fluoride was first added to the drinking water for the victorian town of bacchus marsh in 1962, with melbourne beginning fluoridation in 1977. the towns of portland, nhill, port fairy, barnawartha, and kaniva have naturally occurring fluoride in their drinking water. <P2-S1> in august 2012 approximately 90% of the victorian population had access to fluoridated water. <P2-S2> the fluoridation of victoria's drinking water supplies is regulated by the health (fluoridation) act 1973, by the department of health. <SEP> <P3-S0> "Son of Your Father" is a song by Elton John with lyrics by Bernie Taupin. <P3-S1> It is the fourth track on his third studio album, "Tumbleweed Connection". <P3-S2> The lyrics tell of an argument between two men (one blind) on "an East Virginia Farm." <P3-S3> After a while, their argument leads to death because the two men did not follow the golden rule as stated in the lyrics (but in different words). <P3-S4> It is the only song off "Tumbleweed Connection" John has never performed in concert. <SEP> <P4-S0> the curious location on catalina island stemmed from cubs owner william wrigley jr.'s then-majority interest in the island in 1919. wrigley constructed a ballpark on the island to house the cubs in spring training: it was built to the same dimensions as wrigley field. <P4-S1> (the ballpark is long gone, but a clubhouse built by wrigley to house the cubs exists as the catalina county club.) <P4-S2> however, by 1951 the team chose to leave catalina island and spring training was shifted to mesa, arizona. <P4-S3> the cubs' 30-year association with catalina is chronicled in the book, the cubs on catalina, by jim vitti . <P4-S4> . <P4-S5> . <P4-S6> which was named international 'book of the year' by the sporting news. <SEP> <P5-S0> The Hot 100 and Easy Listening charts became more similar again toward the end of the 1960s and into the early and mid-1970s, when the texture of much of the music played on Top 40 radio once more began to soften. <P5-S1> The adult contemporary format began evolving into the sound that later defined it, with rock-oriented acts as Chicago, The Eagles, and Elton John becoming associated with the format.
