I grew up in a house with one radio and a little old record player so the first time I heard anything operatic was when the radio was accidentally shifted off the racing station to the ABC.
I had never heard anything as beautiful as Joan Sutherland singing the Bell Song from Delibes 'Lakme'. It was written on my wish list but it was 10 years before I tracked down a recording and could afford to buy it on my $20 a week pay.
Then the ABC broadcast the Opera live from the Sydney Opera House and I had my first view of the entire opera story. I loved it and Dame Joan for ever.
