Composer Stephen Sondheim was among the audience last night for the press night of Sweeney Todd at the London Coliseum.
The concert staging starring Bryn Terfel and Emma Thompson is a reprisal of the production that ran to acclaim in New York's Lincoln Center last year.
Lonny Price's production, which also features in the cast John Owen-Jones, Rosalie Craig, Alex Gaumond, Matthew Seadon-Young, Katie Hall, Jack North and Philip Quast, runs for 14 performances until 12 April 2015.
Sweeney Todd comes to English National Opera as the first in a new major partnership between it and the GradeLinnit Company.
Other guests last night included producer Michael Grade, comedian Frank Skinner and ice skater Jayne Torvill.
