With the passing of Michael Jackson, we can say goodbye to an era that started with "The Travelling Minstrel Shows" of the 19th century. In some ways these shows were racist, but in other ways, it celebrated the joy of the oppressed who could relieve their sufferings momentarily with songs and dances. Take a look at Al Jolson and some dancing minstrels doing "Camptown Races". It's both funny and joyous.
It's a rare person who can entertain millions with both singing and dancing. This has brought much happiness and excitement to many.
In the words of Charlie Brown's dog Snoopy, "To live is to dance and to dance is to live".
