In the video, Marx is seen playing for the Chicago Cubs against the Oakland A's, in the seventh game of the World Series (Marx is a Chicagoan and a noted Cubs fan). In the classic baseball clutch situation—last of the ninth, two outs—Marx faces A's star relief pitcherDennis Eckersley (who plays himself). The baseball scenes (complete with announcer Bob Uecker, who also plays himself) are intercut with Marx and his band playing the song on the field of the A's ballpark, the Oakland Coliseum.
Finally, with two strikes on him, Marx slams a home run to win the game for Chicago, to the dismay of Oakland players Rickey Henderson and José Canseco (who make cameos, as does Cubs manager Jim Lefebvre). Then we see a dozing Marx shaken awake; his homer was just a dream. (However, since the game was played in Oakland, the hometown A's would still bat in the bottom of the ninth, so Marx' homer could not have won the game for the Cubs. It should also be noted that both the Cubs and Athletics are wearing their respective home uniforms in the video, even though the stadium is clearly Oakland-Alameda County Coliseum)
