Salvatore "Sam Sings in the Night" Catalanotte (born Salvatore Catalanotto; 15 February 1893 – 14 February 1930) was an Italian-American mobster, and boss of Detroit's Unione Siciliana from 1920 to 1930.
"Sings in the night" is a translation of a close misspelling of his last name (from the Italian "caNta la notte").
