Is that a women singing?

This has been bothering me, im sure your all familiar with the song "All Out Of Love" by Air Supply, if not heres the link YouTube - All out of love - Air Supply
anyway, ive heard the song many times before ive seen the video, and ive always thought the chorus was sang by a woman, then i saw its video and it was a guy singing.

I listened to it again but i couldnt hear a mans voice under, so im wondering if hes just lipsinging or his voice is just effeminent.
Did anyone else think it was a women or is it just me?

I made the poll multiple choice so that you could choose one of the first two options, and one of the last three.

Its just a man/men singing high I think. They often sound feminine when they do.

It's a man.

Air Supply's style of soft rock...

Now if you were talking about Grace Jones, then the answer would be yes.

I probably would've thought it was a woman too when the dude with the big black hair comes on xD

Yeah I always figured it was a woman.
