Bei Mir Bistu Shein (Yiddish: בייַ מיר ביסטו שיין, "To Me You're Beautiful") is a popular Yiddish song composed by Jacob Jacobs (lyricist) and Sholom Secunda (composer) for a Yiddish musical, I Would if I Could (in Yiddish, Men Ken Lebn Nor Men Lost Nisht, "you could live, but they won't let you") in 1932 that closed after one season. Secunda sold the publishing rights to the song for a mere US$30. The original Yiddish version of the song (in C minor) is a dialogue between two lovers who share lines of the song. A common soramimi of the title is "My Dear Mister Shane".
