Some pictures from the 40th anniversary gala in Los Angeles. This was broadcast on local radio and is available for download from the internet...I read somewhere, forget where, that it was also being captured for later TV broadcast.
There is a clip here from some Boston TV programme. I would suggest that this is only for the very obsessed fan. I'm trying to work out what is worse, the substance or the form. Far too much of the clip is taken up by some halfwit in the TV studio interviewing the reporter; the studio halfwit's research seems to have been purely from the article in the local rag written by someone who attended only part of the concert (if he attended at all). They both make references to 'the soprano' without ever naming her - Ana Maria Martinez. They express surprise that she was 'strong', obviously oblivious that she sings regularly in the top opera houses in the world.
As for the form, in order to see it you have use the media player of the choice of this TV station, not of your choice. They choose to force you to use a virus. Download the virus if you must, but don't attempt to do anything else on your PC once you have downloaded it. Watch the clip, and then go to your 'system restore' and delete all traces of the virus from your PC. Otherwise you will find that some of your programmes and plug-ins have been hijacked, others deleted and others will fail to work. Don't say you haven't been warned that you won't get back that hour of your life.
