Some context: Finian's Rainbow is a musical with a book by E.Y. Harburg and Fred Saidy, lyrics by Harburg, and music by Burton Lane, produced by Lee Sabinson. The original 1947 Broadway production ran for 725 performances, while a film version was released in 1968 and several revivals have followed. Finian moves to the southern United States (the fictional state of Missitucky is a combination of Mississippi and Kentucky) from Ireland with his daughter Sharon, to bury a stolen pot of gold near Fort Knox, in the mistaken belief that it will grow. A leprechaun follows them, desperate to recover his treasure before the loss of it turns him permanently human.
The sharecroppers begin unpacking extravagant gifts to themselves from their new accounts. Sharon and Finian celebrate the end of class-distinction that comes with wealth ("When the Idle Poor Become the Idle Rich"). Shears and Robust show up wondering when the gold will be discovered that will pay for the credit. Woody and Finian explain that there is no need to dig the gold up, since the news has led to massive investment in their tobacco label. Buzz and the Sheriff, however, accuse Sharon of using witchcraft to turn the Senator black. Woody orders them off. He and Sharon agree to marry ("Old Devil Moon [Reprise]"). Susan the Silent watches them, and dances by herself, and discovers the hidden gold ("Dance of the Hidden Crock"). She takes the gold for herself and hides it.  Meanwhile, the still-black Senator Rawkins is hiding in the woods. He meets Og and explains what happened to him. Og decides what the Senator needs is a new inside rather than a new outside. He uses his own magic to make the Senator a nicer person ("Fiddle Faddle"). In his new persona, Rawkins falls in with a group of black gospel singers looking for a fourth man ("The Begat"); by chance, they are all going to sing at Woody and Sharon's wedding. The wedding is interrupted by Buzz and the Sheriff, who have come to arrest her for witchcraft. The Senator tries to defend them, but as a black man the Sheriff has no need to heed him. Finian steps in, promising Sharon can change the Senator back. He dismisses everyone, intending to use the Crock to undo her wish, but finds the crock gone.  Og, now almost human, looks for Sharon to tell her his feelings. He finds Susan instead, but realizes he is also attracted to her. He wonders if all human love is so fickle ("When I'm Not Near the Girl I Love"). Finian finds them and tells them Sharon is in danger. When Og reveals he doesn't have the gold, Finian runs off in despair. Susan knows where the gold is, but can't speak. Frustrated, Og wishes she could talk, not knowing the gold is under his feet. Susan speaks, and tells him she loves him. Og realizes there is only one wish left, and if he uses it to save Sharon he cannot be a leprechaun again. He is unsure what to do until Susan kisses him. Deciding being human isn't so bad, Og wishes the Senator white again.  The Senator promises to be a better representative to the people, and the Sharecroppers welcome Og and the now-verbal Susan ("If This Isn't Love [Reprise]"). Finian, however, has lost the crock and his hope of getting rich. Seeing that Sharon and Og have found their dreams, he goes off again in search of his own rainbow, saying 'Maybe there's no pot of gold at the end of it, but there's a beautiful new world under it.' The cast tells him goodbye, promising to see him in Glocca Morra ("Finale").

Some context: Richard Hirschfeld Williams (May 7, 1929 - July 7, 2011) was an American left fielder, third baseman, manager, coach and front office consultant in Major League Baseball. Known especially as a hard-driving, sharp-tongued manager from 1967 to 1969 and from 1971 to 1988, he led teams to three American League pennants, one National League pennant, and two World Series triumphs. He is one of seven managers to win pennants in both major leagues, and joined Bill McKechnie in becoming only the second manager to lead three franchises to the Series. He and Lou Piniella are the only managers in history to lead four teams to seasons of 90 or more wins.
After spending 1970 as the third base coach of the Montreal Expos, working under Gene Mauch, Williams returned to the managerial ranks the next year as boss of the Oakland Athletics, owned by Charlie Finley. The iconoclastic Finley had signed some of the finest talent in baseball - including Catfish Hunter, Reggie Jackson, Sal Bando, Bert Campaneris, Rollie Fingers and Joe Rudi - but his players hated him for his penny-pinching and constant meddling in the team's affairs. During his first decade as the Athletics' owner, 1961-1970, Finley had changed managers a total of ten times.  Inheriting a second-place team from predecessor John McNamara, Williams promptly directed the A's to 101 victories and their first AL West title in 1971 behind another brilliant young player, pitcher Vida Blue. Despite being humbled in the ALCS by the defending World Champion Orioles, Finley brought Williams back for 1972, when the "Oakland Dynasty" began. Off the field, the A's players brawled with each other and defied baseball's tonsorial code. Because long hair, mustaches and beards were now the rage in the "civilian" world, Finley decided on a mid-season promotion encouraging his men to wear their hair long and grow facial hair. Fingers adopted his trademark handlebar mustache (which he still has to this day); Williams himself grew a mustache.  Of course, talent, not hairstyle, truly defined the Oakland Dynasty of the early 1970s. The 1972 A's won their division by 5 1/2  games over the White Sox and led the league in home runs, shutouts and saves. They defeated the Tigers in a bitterly fought ALCS, and found themselves facing the Cincinnati Reds in the World Series. With the A's leading power hitter, Jackson, out with an injury, Cincinnati's Big Red Machine was favored to win, but the home run heroics of Oakland catcher Gene Tenace and the managerial maneuvering of Williams resulted in a seven-game World Series victory for the A's, their first championship since 1930, when they played in Philadelphia.  In 1973, with Williams back for an unprecedented (for the Finley era) third straight campaign, the A's again coasted to a division title, then defeated Baltimore in the ALCS and the NL champion New York Mets in the World Series - each hard-fought series going the limit. With their World Series win, Oakland became baseball's first repeat champion since the 1961-62 New York Yankees. But Williams had a surprise for Finley. Tired of his owner's meddling, and upset by Finley's public humiliation of second baseman Mike Andrews for his fielding miscues during the World Series, Williams resigned. George Steinbrenner, then finishing his first season as owner of the Yankees, immediately signed Williams as his manager. However, Finley protested that Williams owed Oakland the final year of his contract and could not manage anywhere else, and so Steinbrenner hired Bill Virdon instead. Williams was the first manager in A's franchise history to leave the team with a winning record after running it for two full seasons.
