That concludes our viewing on ABC television for tonight. We hope you'll join us tomorrow evening when at 7.30 we continue our documentary series Vietnam, a television history. At 8.35, Strangers and Brothers, set in London in 1936. At 9.30, Basil Davidson examines closely three different communities in Africa mastering a continent. At 10.30, a profile on superb dancer Rudolf Nureyev. And in World of Music at 11.20, we feature the music of Elgar, Vivaldi and Mendelssohn in the 20th annual Yehudi Menuhin Festival. In the meantime, thanks for your company tonight. Have a lovely Sunday. Good night.
