Worse was the chorus in The Italian girl in Algiers which began "Weigh anchor". It didn't change and caused such hysterics (not to mention widespread finger pointing) that I came to think it had been deliberate.

The score for Miller's ENO production of Rigoletto originally had "Ah, soul in heaven" as the first line of the final duet. It didn't stay that way.

Beyond me, I'm afraid.

Good to be here. Finding you and so many familiar 'faces', it makes one realise what a hole was left by the destruction of Twitter! Better late than never...
