I first heard the song about 2 years ago from a friend of mine whom i've now lost contact with. I really think the start goes:
I dream't i saw a legend just the other night
At the yankee stadium underneath the light
I heard a man speaking after years and years in jail
His name it was Mandela and he came to tell his tale,

After that words like 'south african cell'
'the crowd they cheered him ? and then the silence fell
'their names i could not tell' come to mind
Its only bits and pieces i can remember,
sorry the information is so vague
