Page 1 of Name that song.. please?!

I heard this tune on a mobile on the train the other day, after 10 minutes realised it was the same song that Cher, Winona + a young Christian Ricci dance around to at the end of the film Mermaids, but can`t remember who sang it?

Obviously it`s not important in any way but i MUST know...!

Very likely to be one of these - but not having seen the film myself I`ve no idea which one.....sorry :-)

Didn`t it go something like

If you wanna be happy for the rest of your life,
never make a pretty woman your wife,
so from my personal point of view,
get an ugly bird to marry u!

"If you wanna be happy" by Jimmy Soul.

thankyou, thankyou, thank YOU!

..I can get on with work and fix this bug now, but I wouldn`t count on it...

Didn`t an eighties novelty/one hit wonder band have a hit with this in early 80`s?
