You've Got Mail (1998)

Continuity mistake: When Joe is on the yacht talking to his father, Joe is mixing up martinis, pours them, and adds an onion to one, and then an olive to the other. The camera cuts away to his father and then cuts back and now the second martini has no olive, so Joe adds an olive again. (01:30:11)

Person in Theatre: Do you mind?
Frank Navasky: A hotdog is singing. You need quiet while a hotdog is singing?

Trivia: Meg Ryan's bookstore is called "The Shop Around the Corner." This is a reference to the 1940 Jimmie Stewart/Margaret Sullivan movie of that name, upon which "You've Got Mail" was loosely based.

Question: What song are Meg Ryan and her co-workers singing around the piano and does anyone know where I can find the words online?
