Alexander's Ragtime Band
From the movie Alexander's Ragtime Band (1938). The fictional band of Irving Berlin's 1911 hit, "Alexander's Ragtime Band" is turned into a very fictionalized version of Berlin's life. Society boy Roger Grant (Tyrone Power) ditches the highbrow crowd to play lowbrow ragtime in 1915 San Francisco. He takes the name of the song as the name for his band, and becomes Alexander, too. He adds singer Stella Kirby (Alice Faye), who gets replaced by Gerry Allen (Ethel Merman!). Band member Charlie Dwyer (dapper Don Ameche) is the third member of the love triangle between him and Stella and Alexander. The movie follows them through WWI and after, with a plethora of Berlin tunes at every moment.
