The name won’t mean much to theatregoers, but the sudden closure yesterday of M+H Communications has shocked those in the profession. One of the West End’s three largest marketing and advertising agencies, M+H handled hit shows including Mamma Mia!, The Woman in Black, Stomp, The Rat Pack and When Harry Met Sally as well as venues Sadler’s Wells and the Lyric Hammersmith. Yesterday, adverts were being pulled from several newspapers following rumours that the company owed millions. An email sent to from a former agency employee attempting to provide continuity for various client campaigns confirmed that M+H had gone into voluntary insolvency and is no longer trading, but explained that “work will still continue for our clients with other agencies and through freelancers.”
