The final collaboration between Clay and Gilbert was a three-act comic opera, "Princess Toto", (1876), another vehicle for Santley. On tour and in the West End it attracted mixed notices, both for the libretto and the score. "The Times"s later comment that the piece was "probably surpassed by no modern English work of the kind for gaiety and melodious charm" was not generally shared: a recurring theme in reviews was that Clay's music was musicianly and pleasing but not strikingly original or memorable. At its first London production "Princess Toto" ran for less than a month. A New York production fared still worse. When it was revived in London in 1881 "The Times" commented that the piece had not appealed to audiences in 1876, "accustomed to a more broadly humorous style of extravaganza" and hoped that by 1881 public taste had become more cultivated under the influence of Gilbert's other comic operas. Nonetheless, the revival ran for only 65 performances.
