In March 1979, Lansbury first appeared as Nellie Lovett in "", a Stephen Sondheim musical directed by Harold Prince. Opening at the Uris Theatre on Broadway, she starred alongside Len Cariou as Sweeney Todd, the murderous barber in 19th century London. After being offered the role, she jumped on the opportunity due to the involvement of Sondheim in the project; she commented that she loved "the extraordinary wit and intelligence of his lyrics." She remained in the role for fourteen months before being replaced by Dorothy Loudon; the musical received mixed critical reviews, although it earned Lansbury her fourth Tony Award and "After Dark" magazine's Ruby Award for Broadway Performer of the Year. She returned to the role in October 1980 for a ten-month tour of six U.S. cities, with George Hearn playing the title character; the production was also filmed and broadcast on the Entertainment Channel.
