Faced with the prospect of having to compete with Agujari at the Pantheon, and knowing that her own seria stars were not of the first rank, Brooke decided as a matter of urgency to revitalise the programme of comic opera. Opera buffa had been more or less defunct at the King's Theatre for two years as a result of failures in the recruitment programme. If, as she perhaps already suspected might be the outcome, her untried castrato and his undistinguished partner were to fail to measure up to the Pantheon star, the fortunes of the King's Theatre might end up largely dependant on a successful season of opera buffa.

The extent to which comic opera had been dominant during the six seasons at the King's Theatre prior to Brooke's management can be demonstrated by figures compiled by Petty. This was the era of Lovattini, and during the period of his ascendancy opera seria accounted for only one quarter of all performances. But for the brief revival in the 1769–70 season featuring Guadagni, the disparity would have been even greater.
