Genesis Many To Much Lyrics

Many too many have stood where I stand
Many more will stand here too
The thing that I find strange
Was the way you built me up
Then knocked me down again
The part was fun but now its over
Why can't I just leave the stage
Maybe that's because you securely locked me up
Then threw away the key

Oh mama please would you find the key
Oh pretty mama please won't you let me go free
I thought I was lucky

I thought that I'd got it made
How could I be so blind?
You said goodbye on a corner
That I thought led to the straight
You set me on a firmly laid and simple course
And then removed the road
Oh mama please help me find the way
Oh pretty mama please lead me through the next day
I thought I was lucky
I thought that I'd got it made
How could I be so blind?
(Oh no)
