The celebrated score features favorites such as “Vanilla Ice Cream,” “A Romantic Atmosphere,” “Dear Friend,” and “She Loves Me.” The musical is based on a play by Miklos Laszlo, whose well-known romantic story was the basis for the 1940 James Stewart film “The Shop Around the Corner,” the 1949 Judy Garland and Van Johnson musical “In the Good Old Summertime,” and the 1998 Tom Hanks & Meg Ryan film “You’ve Got Mail.”
