William Adamson, who managed his own theatre company, had arrived from
Barbados, produced
John Home's
Douglas or the Noble Shepherd and cast Castello in the role of the Young Norval. When Castello performed the role of Lothair in
Matthew Gregory Lewis'
Adelgitha, the author – who was in the audience – complained about the performance. With the death of Adamson that year, his replacement, Mr Burnett, refused to pay Castello the same rate as adult members of the cast, and his last performance with Burnett's company took place in December 1818. In July 1919, he appeared at the
Pavilion Theatre,
New York in the role of Caleb Quotem in
George Colman's play
The Wags of Windsor. However no accounts of further theatrical performance exist until he resurfaced in Kingston Theatre, Jamaica in July 1828 where he delivered
George Alexander Stevens's comic monologue
The Lecture on Heads. In 1829, he joined the
English Company and continued to perform in Kingston. ==Journalist career==
