For many years Richard assisted Richard Brinsley Sheridan in the management of Drury Lane Theatre, and ultimately acquired a share in the property. (The money for this purchase was mainly from the Duke of Northumberland, and on Richardson's death the Duke cancelled the loan.) His comedy, "The Fugitive", was brought out at the King's Theatre in the Haymarket by the Drury Lane Company with success on 20 April 1792, and, when printed, passed through three editions. The prologue was by Richard Tickell and the epilogue by John Burgoyne. Richardson also wrote the prologue to the "Glorious First of June", the after-piece which was acted at Drury Lane on 2 July 1794 for the benefit of the widows and children of the sailors who died at the naval battle of that name.
