A review in Talking' Broadway notes that Brice "comes out swingin' with 'I'm the Greatest Star.'" Howard Taubman wrote in The New York Times "Miss Streisand imagining herself in a radiant future in 'I'm the Greatest Star,' an appealingly quirky song, is not only Fanny Brice but all young performers believing in their destinies".
