My friend Ivor and his girlfriend Joy invited me and Joy's flatmate to this concert. Our seats were in different parts of the RAH - hers Row 1 seat 8 and mine in the Gods. The arrangement was to meet up after the performance at the stage door - Joy, an Australian, was a friend of Joan Sutherland's. So, as instructed, I met Joy, Ivor, the other guest, Sue, and Joan Sutherland at the stage door 50 years ago this year. Two years later, Sue and I were married and still have the front row ticket (£2!) and the programme, signed by Joan. As a celebration, we have optimistically booked to attend the afternoon concert on 23 May.
