"He Didn't Know Exactly What to Do" was changed with each new production (and performer). It was obviously a specialty spot for the character Hans and new numbers were put in to fit the performer.
"Sweetheart, I'll Love You Ever" is not in programs. From the score the Finale was only reprises unless it was changed after 1902.
"How Far a Girl Should Go", "When You At Last Are Mine", and "White Lies" have been traced to sheet music only. They may have been unused or cut prior to the New York opening.
