Verse 1:
Tonight I feel like I'm lost in space
And all the stars above don't seem to guide me
Just when I thought I was safe and sound
The clouds above my head begin to gather
Chorus:
Tonight, tonight
I'm feeling like I might die tonight
Tonight, tonight
And I don't know what to do without you tonight
Verse 2:
Tonight I'm feeling so alone
And I don't know where to turn for help
All I know is that I need you now
More than ever before, more than ever before
Chorus:
Tonight, tonight
I'm feeling like I might die tonight
Tonight, tonight
And I don't know what to do without you tonight
Bridge:
I'm holding on to hope and praying
That you'll come back to me tonight
And when you do, I'll never let you go
Tonight, tonight, my heart is yours alone
Chorus:
Tonight, tonight
I'm feeling like I might die tonight
Tonight, tonight
But until then, I'll love you just like this
