 It took some time for Carte to gather funds for another Gilbert and Sullivan opera, and in this gap Gilbert produced several works including "[[Tom Cobb]]" (1875), "[[Eyes and No Eyes]]" (1875, his last German Reed Entertainment), and "[[Princess Toto]]" (1876), his last and most ambitious work with Clay, a three-act comic opera with full orchestra, as opposed to the shorter works for much reduced accompaniment that came before.Gilbert also wrote two serious works during this time, "[[Broken Hearts]]" (1875) and "[[Dan'l Druce, Blacksmith]]" (1876).Also during this period, Gilbert wrote, "[[Engaged (play)|Engaged]]" (1877), which inspired [[Oscar Wilde]]'s "[[The Importance of Being Earnest]]".
