"If you want me.. I’ll be there for you, if you need me.. just call my name and I’ll be there for you! take the weight of the world, off of your shoulders now, I’ll be there.. to carry you.. to hold you, to hear your voice, to tell you, to tell you everything’s gonna be alriiight, to get you thru the night when you can't be on your own, not alone, not alone, I need to hear you, hear you, hear you, hear your voice, oh carry on, c'mon! Not alooooone!"
