Imagine a time when it all began  In the dying days of a war  A weapon that would settle the score  Whoever found it first would be sure to do their worst  They always had before...    Imagine a man where it all began  A scientist pacing the floor  In each nation, always eager to explore  To build the best big stick  To turn the winning trick  But this was something more...    [Chorus:]  The big bang took and shook the world  Shot down the rising sun  The end was begun and it hit everyone  When the chain reaction was done  The big shots tried to hold it back  Fools tried to wish it away  The hopeful depend on a world without end  Whatever the hopeless may say    Imagine a place where it all began  Gathered from across the land  To work in the secrecy of the desert sand  All of the brightest boys  To play with the biggest toys  More than they bargained for...    [Chorus]    Imagine a man when it all began  The pilot of 'Enola Gay'  Flying out of the shockwave on that August day  All the powers that be, and the course of history  Would be changed forevermore...
