Two of the songs in the play are words written from music straight out of the classic opera Carmen. "To Be or Not Be" is sung to the melody of the "Habernera" aria. The song sung by Polonius "Neither a Borrower nor a Lender Be" was sung to the melody of the "Toreodor" march. The third piece, "Hamlet, Do Be a Lamb" was reported to be set to the melody of Schubert's Baccarole. Who said there was no culture on Gilligan's Island?
