Who is the original singer of "I only want to be with you"?

I found places that tell me different people sing it. I have a version of the song I love it says its by Twiggy but I don't think it is.

that
i dont know what it is that makes me love you?

erm if it is im not sure who it is but ive heard it by dusty springfield and bay city rollers


its a awsome song sing it in choir =]

The only version I know of is the one by Hootie and the Blowfish. Probably not what you're looking for though...

Dusty Springfield
