Geoff:
This is certainly supported by canon.

'"...He (Voldemort) arrived at our house near midnight. my father 
answered the door."
The smile spread wider over Crouch's face as though recalling the 
sweetest memory of his life.Winky's petrified brown eyes were visible 
through her fingers. She seemed to appalled to speak.
"It was very quick. My father was placed under the Imperius curse by 
my master. Now my father was the one imprisoned, controlled. My 
master forced him to go about his business as usual, to act as though 
nothing was wrong. And I was released. I awoke. I was myself again, 
alive as I hadn't been in years."'

(GOF "Veritaserum" p.597 UK edition)

This, as Crouch's description shows later, was before Moody was 
overcome and Crouch Jr. started using the Polyjuice Potion. So Crouch 
Snr. was under the Inmperius Curse well before the World Cup and no 
one noticed any difference.
