How Can You Be Sure Today?

Johnny has a band, Johnny has a bike 
But something is strange in his simple life 
He looks like a sickman, he's got wishful eyes 
And now he tells me that he wants to die
How can you be sure today? 
Give me the gun my friend
How could you be sure? 
Open your mind, never cry 
Just believe in yourself 
Give some light to your life
