The gentle melancholy and lyrical atmosphere of `Twelfth Night` have long made the play a favourite with Shakespearian audiences. The plot revolves around mistaken identities and unrequited love, but is further enlivened by a comic sub-plot of considerable accomplishment. In it, Sir Toby Belch and his companion outwit the pretentious Malvolio, who, despite suffering their most outrageous and insulting practical jokes, emerges as an almost noble figure.
