Mrs Cinderella lyrics

Mrs. cinderella
Please dont pound on my chest
I can not see you now
I can not have seen you before

When it turns twelve oclock
Ill be back by myself
And youll be back in his arms
As mrs. somebody else

Mrs. cinderella
Please dont knock down my door
Youve been around the world
And Ive been around my block

When I hear you say (when I hear you say)
I hear somebody talking (I hear somebody talking)
And when I hear you talking (and when I hear you talking)
I hear somebody say (I hear somebody say)
