The Blane Sisters
Singing sister duo from the film Tin Pan Alley (1940). Alice Faye plays Katie and famed pinup girl Betty Grable plays Lily.
Set in 1915, Katie falls for struggling songwriter Skeets Harrigan, and loans him and his partner Harry Calhoun money to buy a song that will bring success. But Skeets gives it to popular real singer Nora Bayes (played by Esther Ralston) instead, and Katie breaks up with him. The Blane Sisters travel to London and find success there.
