okay, I need some help...

okay, this is the most random post in history, but it is driving me up the wall.

I heard this song in a restaurant the other day and I love it (a very corny song, but I want to listen to it because it makes me smile).

let me set the stage here for it:
-some describe it as 'campy'
-it is more singing, with some beats in the background
-i believe it is sung by females
-i believe some of the lines are spanish
-it is an older song (probably sixties-eighties...not really sure)

okay, so for the most part I think the lyrics go:

'let me say hey now, HEY NOW, hey now, HEY NOW...(something spanish)'

it might be like 'quando quando man hey' but I was in a restaurant and couldn't hear a damn thing.
thanks for your help
