Performer: Trystan Llŷr Griffiths

A fine singing cast gives creditable performances in Johann Stauss II's most famous operetta, but Paul Curran's updating of Act 2 to 1930s Berlin takes the fizz out of the Champagne.

Peter Mumford's intelligent staging concept and a knockout performance by a reduced Philharmonia Orchestra made this a night to remember.

As a hybrid of brilliance and disappointment, this Don Giovanni is in a class of its own.
