歌词∶
There must be lights burning brighter somewhere
Got to be birds flying higher in a sky more blue
If I can dream of a better land
Where all my brothers walk hand in hand
Tell me why, oh why, oh why can`t my dream come true
There must be peace and understanding sometime
Strong winds of promise that will blow away
All the doubt and fear
If I can dream of a warmer sun
Where hope keeps shining on everyone
Tell me why, oh why, oh why won`t that sun appear
We`re lost in a cloud
