The bus is pulling out and I guess I'd better go 
Before I make a grave mistake and let my feelings show 
And twenty miles away she waits alone for me 
But when I try to picture her you're the one I see 
And in another situation I could put up a fight 
But you will be my downfall tonight 

So the night is coming down, drowning us in blue 
And it all points towards the things we know we shouldn't do 
And as I look at you and I fall under your spell 
Well I know I should be thinking of her lying there herself 

And when faced with temptation you know a man should stand and fight 
But you will be my downfall tonight 

Be my downfall be my great regret be the one girl 
That I'll never forget 
Be my undoing be my slow road to ruin tonight 

So the bus is pulling out and I'm grounded here with you 
And I want to say the sweet things babe I've always wanted to 
So tell me now the tail-lights have gone out of sight 
Baby won't you be my downfall once again tonight
