Frank Sinatra's career was struggling at the time and this was made during a period when the only time he did well at the box office was when paired with Gene Kelly.
Kathryn Grayson was considered for the role of K.C. Higgins.
According to Esther Williams in her memoirs, Judy Garland was the original choice for K.C. Higgins but was replaced after she'd become undependable owing to her developing drug habit. June Allyson was also considered but had become pregnant and opted not to work during her pregnancy.
Baseball, The Great American Pastime, never has been widely followed in Britain. Consequently, the film's title for English audiences was changed to "Everybody's Cheering."
Director Busby Berkeley came up with an imaginative swimming number for Esther Williams and Gene Kelly but Kelly didn't want it in the movie. So instead they did "The Baby Doll" number. Eventually the "Baby Doll" number was taken out of the final film.
Rodgers and Hammerstein's ballad, "Boys and Girls Like You and Me," is famous for its three deletions. First, the song was intended as a duet for Alfred Drake and Joan Roberts in the trailblazing 1943 Broadway musical, "Oklahoma!" Then screen rights to the tune were bought by MGM producer Arthur Freed and scheduled to be sung by Judy Garland to Tom Drake in Meet Me in St. Louis. Five years later, the ditty was to be interpolated in this Arthur Freed project, set to be sung by Frank Sinatra to Betty Garrett. The Sinatra prerecording holds a place on the Rhino CD box set, "Frank Sinatra in Hollywood 1940-1964." Still in existence, the Sinatra-Garrett scene has been included on the CD from Warner Home Video.
The final film directed solely by Busby Berkeley.
The idea for the movie was conceived by Gene Kelly, who wanted to pay tribute to the early days of baseball. The movie takes place between 1909 and 1911, as evidenced by Ryan's picture on a new T206 baseball card.
The song "O'Brien to Ryan to Goldberg" (referring to the shortstop/second base/first base double-play) is modeled on a poem titled "Tinker to Evers to Chance" by Franklin P. Adams, referring to the Chicago Cubs infield of 1903-1910.
There was no soundtrack album, but three of the stars made commercial discs of a few songs, on MGM Records. Two Gene Kelly-Betty Garrett duets were recorded , "Take Me Out to the Ball Game" (music by 'Albert Von Tilzer', lyrics by Jack Norworth), done in a swinging tempo, and "Yes, Indeedy" (music and lyrics by Roger Edens, Betty Comden and Adolph Green). Also, recorded on MGM Records, a Garrett solo, "It's Fate Baby, It's Fate" (music and lyrics by Edens, Comden and Green) and recorded on Columbia Records, Frank Sinatra's charming ballad, "The Right Girl for Me" (music and lyrics by Edens, Comden and Green).
