Event Comment: OObrien did Brazen, for his first appearance, & met with great Applause (Cross). [See a two-column comment on The Recruiting Officer and O'Brien's acting in Theatre No II published in The London Chronicle, No. 277, 5-7 Oct., p. 343: "The character of Brazen never existed in human nature, but is merely the child of Farquhar's own licentious invention...and for this reason I imagined it impossible for any actor to appear to advantage in it, without having recourse to that buffoonery and grimace which has always been made use of by the most eminent to support it; but I was agreeably surprised to find myself mistaken: for the young gentleman who has now got it into his possession goes through the whole with a genuine comic spirit; and, by his peculiar method of acting it, in a great measure corrects the unnatural absurdity of the writer." Specific details of his acting as well as comments on other roles are given.] Receipts: #150 (Cross); #174 3s. 6d. (Winston MS 8)
