Swedish (?) song "ata ata ana yay"

[trampy_trev]

Hey guys,

I've just got back from a holiday in Bulgaria where there was this song everywhere, I was told it was Swedish but that was all I could find out.

I don't have a recording or anything but the chorus went (phonetically)

"Tu say le nay, tu say le ata ata ana yay"

It was kinda camp europop, male singers... sort of similar in style to that european hit last year by O-Zone.

I'm desperate to find it, any help would be greatly appreciated. Thank you.
