I Guess Ill Have to Change My Plan by Fred Astaire Lyrics

I guess I'll have to change my plan
I should have realized there'd be another man
I overlooked that point completely
Before the big affair began

Before I knew where I was at
I found myself upon the shelf, and that was that
I tried to reach the moon, but when I got there
All that I could get was the air
My feet are back upon the ground
I lost the one girl I found
